fun fact- at this time Big Canyon’s 3 miles of “continuous slot” is among the longest slot canyons we know of in New Mexico

essay bro

Big Canyon is a tributary to the Rio Gallina within the Chama Canyon Wilderness.  Big Canyon, with tributaries of its own, has over three miles of continuous slot canyon.  The narrow, slot canyon portions of Big Canyon reaches depths of three hundred feet in the lower half mile…!!!   Please right-click-save-as our map below to make yourself a hard copy of your own.

 

We drive in about 13 miles to Big Canyon on Forest Road 8 from Gallina, NM.  We turn off onto the tiny, unmarked Big Canyon access road shown on the map below, and park a ways in.  We hike north to... and then- thru a narrow canyon of solid alabaster.  The alabaster layer in this area is one hundred feet thick…!!!  The 60’ drop seen on the map below is sandstone and a dangerous down-climb is do-able on the south side of the fall.  One half mile below this is the confluence of South Fork Big Canyon which is yet to be explored.  In another quarter mile or so is a side canyon we call “Tunnels” which has two forks.  Both forks have extremely narrow slots, requiring even a skinny guy like me to turn sideways...!!!  see photos below.  Natural tunnels occur here.

 

Soon after this, there is a 10’ drop, not shown on the map below, requiring a short rope, which we use tying knots for hand and foot holds.  Farther along we encounter an under-cut 30’ drop requiring a free hanging rappel (see first photo below).   There are no rope-less climb-arounds at either of these drops.... and between these two drops is a difficult-to-find ... jug-handle type natural arch -see photos.

 

The half-mile of canyon below this 30 footer is the crux of Big Canyon…the “sweet” corridor… (see top photo above).  Midway in this section is a 12’ high drop that can be climbed around without a rope.  Downstream a short ways is Cheerio Arch.  It is about head-high on your ight.  Upon reaching the mouth of Big Canyon, beautiful and grand Gallina Canyon will greet you.  It is a 1500’ deep canyon with a broad bottom.  However there is only about a mile and a half of public forest land to enjoy here on the canyon bottom.  The rest of the canyon bottom is private land owned by Gallina Canyon Ranch…both upstream and downstream.

Gallina Canyon Ranch a great way to visit and enjoy these amazing “slot canyons” of the Chama Canyon Wilderness.  Several amazing slot canyons are easy to visit with normal hiking from here.  In fact, vacationing at Gallina Canyon Ranch will put you in the heart of slot canyon country...!!! ...AND- you will be in a great position to visit some of the best parts of some of the best slot canyons in New Mexico, without technical rock climbing and repelling equipment or even having much canyoneering experience.  Gallina Canyon Ranch is truly amazing and is the only easy hiking access to this western portion of the Chama Canyon Wilderness.   

 

…and as yet none of the tributaries have been explored.

This photo shows a 30’ drop in the lower portion of Big Canyon.  It is here that Big Canyon turns into an amazingly sculpted, very deep and narrow slot canyon.  This 30’ drop is greatly undercut requiring a “free-hanging” repel.  There is a strong healthy ponderosa nearby to use as an anchor.

 

This photo shows the knotted rope we used to descend a 10’ drop by hand

 

…a colorful sculpted stretch of Big Canyon Slot above the 30’ drop

 

Cheerio Arch is in the lower section of Big Canyon

 

The Chalkstone is wedged into place 30’ overhead in the lower reaches of Big Canyon

 

…a more open area… wheeet-wheew… a half mile or more above the 30’ drop.

 

This small jug-handle arch is between the 10’ and the 30’ drops...

 

A manadory sideways squeeze allows passage thru a tributary called “Tunnels”...see map above

Both of these narrow slots in the Tunnels area are solid and amazing alabaster

This area is called “Tunnels” because of natural tunnels created by slumping, massive alabaster blocks.  It is a wonder that a passage with head-room remains open here

...and a 100 foot high wall of strata sandstone blocks the canyon above the Tunnels
