The granite that makes up Pikes Peak and the surrounding mountains that you can see from Crystal Reservoir was once molten rock. It slowly cooled and hardened miles beneath the surface, providing the crystals a very long time to grow. Over the last 500 million years numerous tectonic plates have collided forcing the now-cool granite lying below the surface upward. Around 65 million years ago a tectonic plate under the Pacific Ocean was driving into the North American continent which initiated tremendous, mountain building pressure below what is now Colorado and created Pikes Peak.
From two million to 10,000 years ago a series of Ice Age climates gripped the land. Alpine Glaciers formed on Pikes Peak. These rivers of ice gouged bowl-like hollows and U-shaped valleys. Since then, erosion has continued to sculpt the rugged mountain.
To earn credit for this Earthcache, please email me with the answers to these questions. Please do not include answers in your visit log. To assist with these questions, I have included properly labeled rock samples collected from this area.
Q1. How many u-shaped valleys can you identify from your present location (GZ)?
Q2. When you examine a piece of Pikes Peak granite you should be able to see evidence of a white material, a pink material, and possibly a clear shiny material. Name each material.
Q3. What do these crystals in the granite tell us about the rock’s origin?

06/30/2019 By Paperballpark #4750. I was up here today for the PPIHC, so I thought I'd take a moment to do this cache while here. I wasn't so sure about the valleys, but I've tried, and sent my answers to the CO. Amazing scenery here. TFTC!
06/28/2019 By kristen016 Took the trip up to the summit today... will send answers when I have better internet!
The Bride and I had weddings in Kansas City on June 21st and then another one in Omaha on June 29th. I told her I really wasn’t interested in driving to Kansas City and driving home for 9 hours and then a few days later drive all the way back same direction for 13 hours. So we decided we would take a mini vacation in between weddings and head to Colorado for a week. We rented a car, but little did we know the car was going to be a Cadillac sedan, and I’m thinking this is going to be my caching mobile for this trip.
###So over the course of the 11 days, we visited 10 states. I was able to get 5 caches that were Year 2000 including Mingo. I was able to get the oldest cache in 3 states…Kansas, Colorado and New Mexico. Colored the state of New Mexico RED and put 3940 miles on the rental car. ###
This trip started out in Kansas City as the wedding was on Friday. So we cached the morning of Friday and did the Powercat challenges near Gladstone area. Loved walking the sidewalk, we did get a downpour on us, so hoped into a local spot for lunch and then once the rains lifted we went hiking again. Then went to the wedding on Friday night. Then next day on Saturday, went caching with Gnomecat, Louinliberty and Debrajean grabbing a few caches that I had handpicked out. Was great to see my KC friends for the 2nd weekend in a row after the previous week in Indiana and by the end of this trip it will be 3 weeks in a row. Had an amazing dinner at Gnomecats and enjoyed the great hospitality.
Then on Sunday June 23 is where the journey begins. We headed towards Colorado Springs and grabbed Mingo on the way there. This day was about 9 hours of driving and grabbed a few caches in the Colorado Springs area before meeting up with friends in the afternoon.
Monday June 24 was always going to be a big day both driving and hiking. We started it off by going to Paul Barkley (2nd 2000 year cache). Got lucky as that section of the park was closed to people on Tuesday due to electric work being done. Then from there the Cadillac took us to Geocache (3rd 2000 cache). Then after that we headed to Albuquerque, New Mexico.
Tuesday June 25 we cached in Albuquerque in the morning doing a few wherigos and then headed over to the oldest cache in the state. Found the place to park and made the short hike up the hill. Then went across the way and did the Hangman hiking series. After we completed that we headed to Santa Fe to visit and then back to Colorado Springs.
Wednesday June 26th, we got up and headed off to Tarryall (4th 2000 year), those that get nervous about driving well the Cadillac made it just fine. After that we headed to Pikes Peak, it opened late because the car race practice was that morning. We drove up to mile 16 and then shuttle to the top because of the renovations to the new visitor center at top. After this we are now heading back East. We get to Kansas and find Airakee and then spend the night in Kearney. I was able to watch on the phone Vanderbilt win the World Series…Go Vandy Boys
Thursday June 27, drive to Omaha and meet the KC crew for the 3 week in a row and we drive to Sioux Falls to get the State Bird.
Friday June 28th, finish the last 21 of the Ficks Fizzy we had left. Bad news was on 61 Gnomecat fell in the ditch and went over his head in the water. The ditch had probably 8ft of water. Then headed to Omaha and did some challenges and parted ways
Saturday June 29th, some light caching before wedding and then came home on Sunday 13.5 hour drive.
Thanks to all the hiders. Earthcaches and Virtuals have sent answers. Challenges will either have a picture or available via public profile. Was able to leave my signature pencil in a few caches. Thanks for the cache-signed log.
06/20/2019 By Saint Aubie We stopped on the way up the mountain today. This is the first time I've been back since I was a teen, and I remember the reservoir being full! It was really low today. Read the informational signs, took a few pictures, and continued our journey. Answers sent; tftc
06/13/2019 By SpanDino 0407p , fs 2.5 ; stopped here on the way down.
08/21/2018 By J&Leebee Here from Yorktown VA for a few days on business and then some geocaching in my free time. Headed up to Pikes Peak, but got hit by a storm that blew in with heavy, heavy fog. With limited visibility I was able to get most of the info for logging this cache (answers emailed separately per your instructions). TFTC and making geocaching in Colorado an awesome experience!
08/17/2018 By Beamer62 Great morning fishing and kayaking. Checked out cache before heading upwards! BlackJack59 sent answers.
08/17/2018 By blackjack59 Spent the morning at the lakes with Beamer62. We fished for a while and then headed on up to the top of the Peak. What a great place and thanks for a well done Earth Cache!
08/07/2018 By f1ipper Stopped by to gather the information and then proceed on.
07/28/2018 By bfoust Stopped on the way down from the peak and collected the information. Thanks!
