A very interesting geological feature involving volcanic eruption and erosion. There is a $5.00 day use fee for entry into the monument, or Golden Age Pass is accepted (for us old folks) Winter Hours - Nov 1 to March 10: 8am to 5pm gates close at 4 pm Summer Hours - March 11 to October 31: 7am to 7 pm gates close at 6 pm. Visitors must be out by closing time.
The coordinates will bring you to a parking area in the Kasha-Katuwe Tent Rocks National Monument where you will hike into a slot canyon to observe the effects of volcanic and erosion elements.
The cone shaped tent rock formations are the products of volcanic eruptions that occured 6 to 7 million years ago and left pumice, ash and tuff deposits over 1,000 feet thick. Tremendous explosions from the Jemez volcanic field spewed pyroclasts (rock fragments), while searing hot gases blasted down slopes in an incandescent avalanche called a "pyroclastic flow." In close inspections of the arroyos, visitors will discover small, rounded translucent obsidian (volcanic glass) fragments created by rapid cooling. Please leave these fragments for others to enjoy.
Precariously perched on many of the tapering hoodoos are boulder caps that protect the softer pumice and tuff below. Some tents have lost their hard, resistant caprocks and are disintergrating. While fairly uniform in shape, the tent rock formations vary in height from a few feet to 90 feet. As a result of the uniform layering of volcanic material, bands of grey are interspersed with beige and pink-colored rock along the cliff face. Over time, wind and water cut into these deposits creating canyons and arroyos, scooping holes in the rock, and contouring the ends of small, inward ravines into smooth semi-circles.
To log this cache you need to email the answers to 2 questions that can be found on educational signs along the trail:
1- How were the deposits formed?
2- What do geologists call the deposits?
Not required but please send us a picture of you at SC12, one of the education stops along the slot canyon. The terrain to this point is rated at 2.5, if you decide to continue to the top of the mesa it would be rated a 4. The views from the top are worth the 600 ft climb.
This is a sample of the picture you can post.
