0217 - water flowing W in Oak Creek, note water-slickened rock and standing water indicating
	higher flow
0225 - looking NW (telephoto), "knob" is Gano Peak, an igneous intrusion, beyond and to the left
	of it is a small mesa just beyond which is the junction between the West Road and Maxwell
	Scenic Drive, the N edge of Burro Mesa is hilly area to left of mesa at about the same
	distance
1352 - debris from rock falls off Vernon Bailey Peak
1353 - conglomerate-like alluvium exposed by Oak Creek
1354 - looking N toward Vernon Bailey Pk. Linear structure prob due to jointing
	not dike
casagrande-strat - authors disagree on identification of layering. McGookey (Geologic Wonders
	of W TX) ids what appears to me to be the BMB (34-30 My) as part of Pine Canyon. McCloud
	(Big Bend Vistas) divides cliff into two with upper half being ash flow tuff (EP?) and
	bottom Lost Mine. Spearing (Roadside Geology of TX) ids layers only as either rhyolite
	or basalt. Looks like material between my BMB and PC on left (N) side of peak, which
	would be Chisos. I see no reason to divide cliff in two.

Burro Mesa Rhyolite --> Emory Peak Rhyolite, quartz-bearing rhyolitic ash-flow
			tuffs, 32 Ma. A series of E and NE trending dikes of
			chemically identical rock cut through Chisos Fm and
			younger rocks.
Wasp Spring Flow Breccia and Lost Mine Rhyolite --> Boot Rock Member, quartz
			trachyte to rhyolite lavas, ignimbrites, and maar
			surge deposits, ~32 Ma
Brown Rhyolite --> Pine Canyon Rhyolite, ignimbrite that formed Pine Canyon
			Caldera, 33-32 Ma
