Mud Mountain

Mud Mountain is the closest developed climbing to town, overlooking Truth or Consequences from the limestone folds south of the city. Mountain Project’s own line on it is hard to improve on: a beautiful winter limestone crag. Every route here is well bolted with user-friendly anchors, and — a small distinction we have not found anywhere else in the county — each one carries its own plaque, name and grade, fixed to the stone below the first bolt. Somebody organized and finished this crag with real care, and finding out who is probably the single best interview left to chase for this book.

The rock

Mud Mountain is the southern summit of the Mud Springs Mountains, a small northeast-tilted fault block — about eight kilometres north to south and three across, under 26 square kilometres all told — that was shoved up northwest of the city while the Rio Grande rift dropped the valley beside it. The block is Proterozoic basement with close to a kilometre of Paleozoic platform carbonate stacked on top: Cambrian Bliss Sandstone at the base, then the Ordovician El Paso Group (Hitt Canyon and McKelligon Formations) and Montoya Group (Cable Canyon Sandstone, Upham, Aleman, Cutter), then the Devonian Percha Formation — the Mud Springs are among its northernmost outcrops — and finally some 500 metres of Pennsylvanian limestone: the slope-forming Red House Formation and, above it, the Gray Mesa Formation. What this block does not carry is the Silurian Fusselman Dolomite or the Mississippian Lake Valley Formation, both of which the Caballo Mountains hold across the river. That absence is the local signature: two fault blocks eight miles apart, two different readings of the same sea.

Which unit the four walls are actually cut in we are not going to print as fact until somebody opens the Cuchillo 7.5′ quadrangle (Maxwell & Oakman, USGS GQ-1686), which maps this ground. The best candidate is the Whiskey Canyon Member of the Gray Mesa Formation, early Desmoinesian Pennsylvanian, described in the literature as the range’s principal cliff-forming cherty limestone; the Ordovician carbonates lower in the block are the alternative. Single-pitch sport walls rather than a 300-foot escarpment fit the Pennsylvanian cliff bands. Call it an inference from regional mapping — a good one, but not a finding.

What the rock does under your hands is less ambiguous. Climbers here report variably sharp limestone with pockets, and, on Jasper, thin technical climbing on orange limestone — three textures that are the standard vocabulary of weathered platform carbonate. Sharp grey is fresh rock. Orange is an iron-stained weathering rind. The pockets are solution features: slightly acidic rainwater working along bedding planes and joint flaws and enlarging them, which is why this crag gives pockets and small huecos instead of the continuous crack systems that would have made it a trad venue. Chert nodules in both the Pennsylvanian and the Ordovician carbonate weather proud of the limestone that dissolves around them — good holds, occasionally razor-edged ones, and unyielding to a drill bit. Because carbonate platform rock is layered and the layers differ in hardness, expect bedding-plane ledges and small roofs where a resistant bed stands over a soft one.

Two consequences worth carrying to the base of the cliff. The first is that the crag is new, and Mountain Project says so plainly: some climbs still have loose rock, and care should be taken to protect people standing below. A freshly developed limestone crag sheds its weathering rind for several seasons — wear a helmet. The second is that bolts hold beautifully in sound platform limestone and badly in the soft punky orange rind, which is one more reason to trust the plaque-marked lines of whoever built this place rather than improvising your own.

Four walls

The crag unfolds wall to wall along the hillside, 41 routes across the four of them. Winter Wall (19 routes, 5.8–5.12), reached first, is the standout — south-facing, sunny most of the day, with shade creeping in from left to right starting around two in the afternoon come December; by four it has swallowed much of the left side. A short, easy down-climb along the base leads to Crow Feather Wall (13 routes, 5.8–5.12). From there, a trail across the scree at the bottom of the down-climb reaches Yellow Wall (2 routes); continuing up the switchbacks along Crow Feather instead reaches Vacation Wall (7 routes). Grades on Yellow and Vacation Walls beyond the overall 5.8–5.12 range were not recovered.

Approach & access

The drive is now known in enough detail to print. Go under the interstate and zero the odometer; head up over the dam. At 1.4 miles, turn right into a large arroyo marked by a cairn and follow the tracks 0.5–0.6 miles to a doubletrack on the left, climbing onto the mesa; follow that to the water tank and park — 2.9 miles total. Upper parking is possible from there with a high-clearance 4WD. From the parking area, follow cairns along the ridge, then down across a wash to the first wall. Land status at the crag remains unconfirmed; given how close Mud Mountain sits to the city, some mix of BLM, State Trust and private ground is plausible, and that stays an open question until our own visit closes it.
