    Yosemite back to geocaching homepage     May 21, 2004 This was such an amazing weekend! 
    We arrived in Yosemite Thursday night with our friend, Linda. We were all 
    staying at the Curry Village. Friday morning, Jimmy, Linda and I had 
    breakfast with Eric, Lauree, Jim, Bambi, Dave, Nancy, Terry, Amy at the 
    Curry Dining Pavilion. Around noon, everyone split up to do their own 
    adventures. Eric stayed in the village to wait for everyone to come in. Dave 
    Retz went out exploring on his own. Terry and Amy went up to Glacier Point. 
    Lauree, Jim, Bambi, Dave, Linda, Jimmy and I all headed to the Happy Isle 
    trailhead. For our first geocache today, all 7 of us helped to find it: A 
    Happy Place. We introduced Bambi and Dave to geocaching. Lauree, Jim and 
    Linda have heard about our previous adventures so they were curious about 
    what it entails. Since Yosemite is a National 
    Park, there are no physical caches allowed in the park, so all of the 
    geocaches we did this weekend are called virtual geocaches, which means you 
    need to find the answers to something rather than a container. The text in the smaller font is 
    information from the geocache owner.

        This is a 
        beautiful geocache location with a fun challenge. 
        I like things 
        that are happy. This is a happy place despite some recent local 
        disasters. 
        The structure 
        you are standing on is still in good shape despite a nearby massive 
        rockfall and windblast in the Happy Isles area that damaged the nearby 
        Happy Isles Gauging Station Bridge in July 1996. Then a major flood in 
        January 1997 caused extensive damage to human-made structures along the 
        main stem of the Merced River, including that same Happy Isles Gauging 
        Station Bridge. That bridge was removed for safety reasons and the 
        Gauging Station will be relocated in the future. 
        Huge rocks 
        were embedded in the trunks of hundreds-year-old trees, as if the trees 
        were mere clay. Giant trunk carcasses were strewn about as if they were 
        straw. 
        But this 
        structure you are standing on survived it all unscathed. 
        Enjoy the view 
        and enjoy the cache hunt. 
        TO GET CREDIT 
        FOR THIS VIRTUAL CACHE, EMAIL TO ME ANSWERS TO THE FOLLOWING QUESTIONS:1. Who loved Joey in July of 2003.
 2. During the flood of 1997, on what date was the high water marked.
 3. How high up your body was the water on that date. (You can give an 
        approximate measurement or tell me which part of your body would have 
        been above the water.
 
        After you 
        email me your answers, go ahead and log your find. Please do not enter 
        the answers in the logs. 
        Please remove 
        any trash you find in the area.   
        Linda, Jimmy and I started hiking to the 
        Happy Isle trailhead from Curry Village and coincidentally ran into 
        Lauree, Jim, Bambi and Dave when we arrived. When we met up with them, 
        we also saw a coyote! He was completely un-phased by us and just 
        strolled along as if our presence was normal. Since they were with us, 
        they all decided to stay and help us find our first geocache of the day. 
        We also ran into 2 other cachers looking for this

            jretz (16 found) Walked in from Curry Village, enjoying the cool weather. We had a 
            team of 7 of us for this cache, 5 who had never geocached before! We 
            enjoyed having them with us and perhaps turned them into cachers as 
            well!
 While we were standing on this structure, we ran into 2 other 
            cachers: geo_hiker. This was the first time we've ran into other 
            geocachers so it was fun chatting with them a bit.
 Thanks!

            Split Rock: An Investigation 
            N 37° 
            43.854 W 119° 33.509 
            
            
            link to the geocaching website 
            This is a 
            marvelous opportunity to see a large boulder close up just after it 
            has had a major slab split from it. 
            "Sometimes 
            rocks weather by peeling off in sheets rather than eroding grain by 
            grain. Exfoliation is scientific Latin for that process. It can 
            happen in paper-thin layers on individual boulders, or it can take 
            place in thick slabs as it does here, in Yosemite Valley, 
            California." 
            "The great 
            white granite domes and cliffs of the High Sierra, like Half Dome, 
            owe their appearance to this type of exfoliation. These rocks were 
            emplaced as molten bodies, or plutons, deep underground, raising the 
            Sierra Nevada range. Erosion then unroofed the plutonic rocks and 
            took away the pressure of the overlying rock. As a result, the solid 
            rock acquired fine cracks through pressure-release jointing. The 
            combined work of gravity, weathering, plant roots, and the expansion 
            of freezing water opened up the joints further and loosened these 
            slabs." Half Dome also had to deal with glaciation. 
            But what 
            happened here? It appears that this slab split from its boulder was 
            accelerated by the sheer impact of this huge boulder with the 
            ground. This slab may have separated upon impact, or it may have 
            separated years later, having been weakened by the initial impact.
             
            It's not 
            often that many of us get to see a rock in this position so close to 
            its initial split. It's amazing to me that more hikers on the nearby 
            trail don't stop in wonder and explore this amazing exhibit of 
            nature. 
            How did 
            this rock split? Do you know the answer? Do you have more 
            information to add to this analysis? Let me know and I will update 
            this geocache web page. 
            TO GET 
            CREDIT FOR THIS CACHE, email to me answers to the following 
            questions:1. Standing at the coordinates and facing the split rock boulder, is 
            the smaller portion of the split to your left or your right?
 2. Standing in that same position, there is a posted sign to your 
            left. What does the sign say?
 
            Please do 
            not log the answers but send them to me via email and go ahead and 
            log your cache. As always, you can email cache owners through the 
            owner's profile above.
 
            Lauree, Jim, Bambi and Dave left us to 
            hike Mirror Lake so Linda, Jimmy and I headed along the Merced River 
            towards the John Muir Trail for this next cache. We spent some time 
            looking at the gauging station and the high water level during the 
            flood on January 2, 1997.

            Yosemite Valley High Water – The 100 Year FloodN 37° 
            44.790 W 119° 35.775
 
            
            link to the geocaching website 
            Not too 
            long ago, Yosemite Valley experienced a remarkable wintertime flood 
            resulting from unseasonable warm rains on top of a substantial early 
            snow pack. This easy 2-mile loop introduces visitors to the heart of 
            the valley and seven waypoints that reflect some of Yosemite’s most 
            scenic wonders. 
            The 100 
            Year Flood was a once in a lifetime experience. Team Gecko happened 
            to be visiting immediately prior to the flood during their nearly 
            annual winter visit in the valley. The tropical rains began a day or 
            so before our departure. The flood resulted from 10 inches of rain 
            over a 6-day period that melted a substantial portion of the snow 
            pack up to the 11,000 foot elevation level. Some of the resulting 
            damage and changes to the valley and Merced River canyon were 
            extraordinary – at least in human terms. Of course, Yosemite Valley 
            has witnessed many and more dramatic natural events over the 
            millions of years of its formation and sculpting. 
            To 
            complete this virtual cache, you will walk or bike or ski or 
            snowshoe around a well-marked path in the heart of the valley. 
            Parking is available very close to the posted coordinates for 
            Waypoint 1. You may also ride one of the free Yosemite shuttle buses 
            from any of the regular pickup points to this starting location. At 
            each waypoint, you will find clues that allow you to determine 
            coordinates for the next waypoint. To confirm successful completion 
            of the course, please email your responses to the questions asked 
            about each stop. 
            Special 
            note: GPS reception in the valley can be variable at times, 
            especially in forested areas and on the south side. Many of these 
            reference coordinates are rounded to nearest .005. The respective 
            waypoints should be reasonably obvious once you are this close to 
            their true positions. 
            
            Waypoint 1: N37° 44.790, W119° 35.775Only a few yards from parking, this sign features a historic photo 
            taken about 1890 of the Yosemite Village site when it was home to 
            the largest Miwok village in the valley. What was the name of the 
            village? Hint: It starts with the letter K. Also on the sign, the 
            date the U.S. Army took over this location is noted as 19a6. Please 
            use the number represented by the letter a to compute the next 
            coordinates.
 
            
            Waypoint 2: N37° 44.45a, W119° 36.a00This site introduces you to a metal sign on a wooden post of a type 
            that will become familiar to you over the course of your tour. It 
            shows the maximum height of the flood at selected locations. It also 
            shows the corresponding time and date as 11:00 p.m. b/c/9d. As 
            before, you will use the numbers represented by b, c, and d to 
            provide you the information needed to compute later coordinates. At 
            a bearing of 240 degrees magnetic, what is the two-word name given 
            the closest building? Hint: the second word is Center.
 
            
            Waypoint 3: N37° 44.c10, W119° 36.000You can follow a bike trail or a riverside path to this location. 
            Here you will be suspended over the famous Merced River, the main 
            watercourse through Yosemite. The damage it caused to valley 
            campgrounds, Yosemite Village, Yosemite Lodge, and the several 
            communities downstream from the park are documented in a popular 
            booklet titled Yosemite: The 100 Year Flood, Movement in Tides. It 
            is available for purchase for $6.00 in the Yosemite Park Visitor 
            Center and the lodge gift shop. At the Waypoint 3 coordinates, you 
            should see a gray sign that warns against certain behavior. What two 
            activities does it indicate are prohibited? Extra credit: What is 
            the name of this bridge?
 
            
            Waypoint 4: N37° 44.485, W119° 35.e10 where e = d - cThis is also a flood level sign. It is immediately adjacent to a 
            wooden sign that shows days and times. What regularly scheduled 
            events does the wooden sign announce? How many 1-inch wooden pegs 
            were used to construct it? Hint: all pegs have two ends but not all 
            of these pegs show both ends.
 
            
            Waypoint 5: N37° 44.495, W119° 35.e20 where e is the same as for 
            Waypoint 4These coordinates lead you to another informative sign a very short 
            stroll away. It reports on restoration activities not directly 
            associated with this flood. What was previously located here and was 
            moved? The dates of the moves are recorded on this sign as 
            19f9-19g3.
 
            
            Waypoint 6: N37° 44.gf2, W119° 35.402You are now viewing another flood marker sign and should be viewing 
            one of Yosemite’s most famous natural features in front of you. A 
            short distance in the opposite direction – to the southwest – is an 
            interpretative sign about the nearby stone bridge. What is the name 
            of this bridge? How many times does it say the bridge has been 
            replaced?
 
            
            Waypoint 7: N37° 44.d52, W119° 35.d43By now, you should be very familiar with the date and time of the 
            highest water. The number represented by d was originally revealed 
            back at Waypoint 2. You will see it again at Waypoint 7, which 
            should be a short distance from where you started. In fact, from 
            here, you could easily catch a ride. What is the single digit number 
            on the adjacent transportation sign?
 
            This 
            completes the tour of Team Gecko’s High Water virtual cache. We hope 
            you enjoyed navigating the course. Have a pleasant and enriching 
            time during your visit to Yosemite National Park.
 
            This was the most complex geocache 
            we've done so far. Having all of the different way points, and 
            having to solve the puzzle to get certain waypoint numbers was a lot 
            of fun! 
            We luckily got off the correct bus 
            stop and headed towards the first coordinates. We easily found the 
            answers, and while we were there headed up to lower Yosemite Falls. 
            After that, we headed to waypoint 2-7. The trail that this cache led 
            us on was great because there were tons of amazing views along the 
            way. Plus we were shocked at how high the water level was on January 
            2, 1997. During breakfast that morning, Nancy was telling us about 
            stories that employees at the Awahnee told her. How there was so 
            much water coming off the granite cliffs that it looked like reverse 
            bathbub flowing into the valley. Everywhere you looked, the granite 
            walls were pouring water, everywhere was a waterfall.

                jretz (16 found) Wonderful cache!! It was a great walk to see parts of the valley 
                that we wouldn't have explored if it weren't for this very 
                interpretive hike. The views along this hike were spectacular. 
                I'd recommend this to anyone who wants to explore the valley 
                floor, see a lot of amazing sites and learn more about the 
                flood.

 May 22, 2004 Today was the day of the "Big" hike. About 50 of our group 
    were going on the trail to Half Dome. Many would go all the way to the top, 
    some would go at their own pace and go up as far as they wanted. Most of us 
    left Curry Village at 5:30 in the morning and walked to Happy Isles. Around 
    6:15, Jimmy and I headed up Mist Trail with Linda, Vanessah and Stan. We all 
    climbed it at our own pace. It wasn't drenchingly wet, but definitely wet 
    enough to warrant a poncho, at least in mine and Jimmy's opinion. Yesterday, 
    we knew that this cache was up here, but since it was so early and we were 
    concentrating on the hike, we forgot about it till we got home. Luckily we 
    knew the answers so we could log our find.

            Trail Cache 
            N 37°

            link to the geocaching website 
            This 
            virtual cache is located at the top of the Vernal Falls Mist trail. 
            Finding the virtual cache is relatively easy, getting there is a 
            little harder, and very wet! 
            Take a 
            nice hike up the Vernal Falls Mist trail to find this virtual cache 
            and a nice view from the top of the Vernal Fall. The trailhead we 
            started at was about 1 mile south east Curry Village, but there are 
            numerous other ways to get to this cache. 
            To log 
            this cache, please identify the two bodies of water you are 
            prohibited from swimming in. Have fun, and watch your footing when 
            the water is running! Don't worry about emailing me to confirm the 
            bodies of water, I trust that geocachers are honorable people. 
            However, feel free to email me with pictures or comments about the 
            hike. Enjoy!

                jretz (16 found) A group of about 50 of us started this hike at 5:30 am. Many 
                headed up to half dome, some just went at their own pace and 
                enjoyed the views. About 1/2 went up the mist trail, the others 
                went up John Muir. We enjoyed finding a cache along the way.
 The two of us used our ponchos as we climbed up Mist Trail, and 
                it was quite wet, but not drenching. Very cold at 6 am, though!!
