I never came across a topo for techos - we just busked it based on stuff we'd seen in photos/videos. There are big roofs with slopey/nighmare topouts, some vertical warmupstype walls under huge roofs, and the first thing you pass on the way in is a steep leaving wall facing into the area, right arete is a good 7b/+ prow and theres a good 7b ramp/dyno thing in the middle, and some sitters on the left. The following problems are at techos if this is of any help orientate yourself:
7a at right side of the main hard roof:
thing under a dry-in-rain roof:
aforementioned 7b ramp/dyno thing (ignore this beta, slap with the left hand)
7b dyno roof
There's an area out the back of techos called psychokiller which also has some good roof shit:
