Also there would have to be some kind of food and water source for small animals available, and something accessible to someone riding on horseback. Most of the pics I've seen in searching such things online show places similar to Devil's Tower. Not what I have in mind at all. Are there smaller buttes that might not be so glamorous that would suit my story setting? Something not on a tourist's most popular places to see? Would it be feasible to make a place like this up and still be able to term it a butte?
Any suggestions will be considered, and any knowledgeable info greatly appreciated.
Western Colorado and Eastern Utah is very much like the landscape you describe. High sharp cliffs as if the land was excavated by supernatural beings.
Closer to the border in Arizona and New Mexico the land is flat with random hills and mountains popping up like pimples on a face. The land is sandy with rocks of varying sizes scattered like pebbles tossed.
Then there are canyons and expansive valleys that cut through the center of Arizona, the ride down and up I-17 makes for a lovely site. Makes you realize how empty and beautiful our nation is.
Of course there is western Texas as well. Around Abilene and Midland the land is wide open, like Kansas except browner.
My MC will be in the SW for a few days at best before heading home to the Midwest. So this would be about the end of winter and going into spring. Think mid to late March or early April.
Does that help?
Buttes don't have to have vertical walls, they are often surrounded by sand that hasn't eroded away yet.
As to the food and water source: There are plenty of streams and springs. It may be pretty arid country but it's not the moon.
Does that work for you?
Pretty much all SW butte and mesa country is high enough to have cool to cold nights year-round (it can get into the low 50s in spring and summer, and below zero in winter), pleasant to chill winter and spring days, hot summer days (90 to 110F is common, 120F isn't unknown) but little rain or snow. When it does rain, the runoff (which doesn't soak in very well due to the lack of soil) can be violent, but brief. You do NOT camp in a wash.
A lot of buttes have a steep dropoff only on one side, or kinda stand out from the surrounding plain like a dock from a warehouse. I gather you need the top to be reasonably accessable for surface travel? Roads in such country are typically scant to nonexistent, but there are usually jeep trails (often extremely rough) and game trails. Vegetation is normally thin grass and brush (which can be thick, and a lot of it stickery), trees are rare to absent. Lots of small animals and sometimes deer and antelope, tho they may not be visible to a townie's eye. Quail and dove and hawks, too. Snakes of various sorts; rattlesnakes are a hazard anywhere there's rocks or brush, especially in early spring. And bugs like nowhere you've ever been (wolf spiders, wind scorpions, regular scorpions, stink beetles, ants, etc, etc, etc. I live in the SoCal desert and it's the absolute most buggy place I've ever seen outside of a swamp. About all we lack are mosquitoes, but further east the deerflies make up for that.)
A good resource -- USGS topo maps and a faster interface for Google's notion of topo maps:

That you so much for all the wonderful info. My head is buzzing at the moment. This whole idea came after watching a couple of western movies last night that carried over into a dream about a man making an important discovery on a butte. But maybe I could change that to somewhere else. Hmmmm. Just thinking out loud and throwing some possibilities around. I've got the seed. Now to plant it and see if it takes root.
Thanks again.
