Another unpublished canyon in the Matkat system is one we named Dump Truck. It’s the east Sinyella Fault arm of the big east tributary arm of Matkat. It was named Dump Truck because the exit was so huge spilling out into the east arm of Matkat in […]
If Olo Canyon is the crown jewel under Great Thumb Mesa, then Panameta Canyon might be considered the Hope Diamond. It has some of the prettiest and tightest Redwall narrows anywhere in Grand Canyon with fluting similar to that seen in some softer rock sandstone slots.
The Colorado Plateau is filled with slot canyons. The […]
Great Thumb Mesa carves a 20 mile arc north into Grand Canyon. It originates on the South Rim about 20 miles northwest of Grand Canyon village. Royal Arch Creek (AKA Elves Chasm) is on the far east side at river mile 118 and Havasu Creek is on the far west side at river mile 157. The Colorado River makes a huge sinuous detour […]
Matkat is a big canyon complex tucked deeply into the West side of Great Thumb Mesa. It is the only way to get from the river level to the Esplanade for 20 river miles in either direction. We passed the exit of this slot climbing up Matkat at least six times before I walked […]
Grand Canyon river runners know Matkatamiba Canyon well (AKA Matkat). More recently, technical canyoneers visit via 150 Mile Canyon. But to backpackers it’s a mystery. How would you get there? The way to Matkat isn’t easy, but the fastest route is off Great Thumb Mesa southeast of Towago Point. No matter how get there, the slot in the Muav […]
Who would have thought that this would be the hardest album to put together yet? In 2008 Todd Martin, Brian Alleyne, and Rich Rudow descended Olo Canyon from the top pioneering the beautiful but difficult North Rim approach down 150 Mile and up Matkat, crossing the river by packraft. It was the hardest slot […]
If the slot we call SOlo is any indication, Grand Canyon might contain a thousand slots. Certainly more than a person could explore in a lifetime. I had a hunch about the Sinyella Fault on the east side as it emptied into Olo Canyon. There is a really fast route to Olo off […]
140 Mile Canyon rests at the northern end of the Great Thumb Mesa. From the rim it casts a deep gash in the Esplanade North into the Colorado River. Any technical canyoneer hears a siren’s call when looking at that magnificent place from the rim. The photo set includes a map that shows the route of the Deer […]
