Alabaster Canyon

See on youtube:

ACA Canyon Rating – 2A III


To our knowledge neither of the two big rappels (250’ & 75’) have ever been done.  Both rappels can be climbed around by lengthy back tracking and scrambling.



Alabaster Slot Canyon, seen in the center of the photo above, cuts into a deposit of alabaster 300’ thick…!!!  The dark narrow crevice shown here is the exit of the slot canyon.  This exit passes thru 25’ high Alabaster Arch...!!!  see more below...

REMEMBER…!!! Alabaster does not hold climbing anchors very well as it is brittle and crumbly…!!!

...but it is very beautiful...!!!

In May 2015 Randy Simons made the first penetration we know of into the upper reaches of Alabaster Canyon.  His photo above is taken within the lower Middle Fork of Alabaster Canyon.  He explored the Middle Fork, East Fork and Little Alabaster Slot Canyon (which is marked with the word “Little” on the map below.)  He and I returned soon after to explore the West Fork, the Elk Trail and 25’ high Alabaster Arch.

essay bro

Alabaster Canyon appears un-named on USGS Topos.  It has approximately three miles of impressive sheer walled canyons of solid alabaster.  The enormous cliff-face shown in the top photo above hosts a 75’ rappel that passes thru a natural arch 25 feet high by 15 feet wide- “Alabaster Arch”.  This rappel must be done with a 200 foot rope because the only available anchor is far upstream. That dry falls/pour-over appears on our topo below with the number 75 by it.  Also, the 15’ high dry falls within the Middle Fork can be easily navigated with a hand-line instead of a rappel.  A hand-line here allows fairly easy ascending and descending alike.


Alabaster Canyon has many tributaries, as you will see on our map below.  Most of the sheer walled canyons here are wonderful “box canyons” a little wider than a true slot.  The West Fork and the last portion above the natural arch both have good narrow “slot canyon” portions.  Another very narrow “slot” is what we call Little Alabaster Canyon.


Little Alabaster Canyon flows parallel to and just east of Alabaster Canyon and it is marked on our topo map below with the word “Little” by it.  The 250 foot high dry-falls / drop-off at the exit of Little Alabaster Canyon happens in three separate tiers... smooth and rounded.  We did not down-climb it but it looks as tho a difficult down-climb is possible...maybe...  The canyon above this drop-off is a very fine and narrow –nontechnical- slot canyon...!!!


Elk Trail is extremely steep but very obvious and well used by hundreds of elk.  It appears on the topo between Alabaster Canyon and Little Alabaster Canyon.  Elk Trail is steep and difficult but it is a breach between the sheer canyon walls and allows non-technical ascending and descending the mountain.  The GPS cords for Elk Trail are: ±36°23.425’N 106°46.674’W at the bottom... while at the top is: ±36°23.283’N 106°46.700’W.


Alabaster Slot Canyon can be accessed from Forest Road 8 above or from two miles west via the primitive parking at the end of Chupadero Road.  We prefer the Chupadero Road access, because the short 2 mile walk downstream in Gallina Canyon to Alabaster Canyon is easy and quite amazing...!!!  Then Elk Trail can take you up into the heart of Alabaster Slot Canyon.  All tributaries are accessible from there.


There is a two-track road shown on the topo map that connects Forest Road 8 above, to the Rio Gallina more than a thousand feet below.  This road is 4WD and develops serious mud during rains... but it does appear to supply a drive-around car shuttle route...however, we have not driven it.

Alabaster Arch, pictured above and below, is 25’ high by 15’ wide and the exit rappel out of Alabaster Slot Canyon passes thru this opening
