Between 31 and 27, just left of a wide crack/chimney is a 5.11 maybe 2 stars.
31 - Midnight At The Oasis 12a. Maybe 2 star. 31a - left of Midnight is a 10d/11a. 32 - Chunky Monkey, 2 pitch, 2nd is 11 and very good. 33 - Tragically Hip 11a. 34 - Twistin Off 10a. 35 - Mashing Cactus
Quite a way right of 32 is a long (maybe 2 pitch) 5.11. Upper part is good but maybe still loose.
Across from the Oasis are 2 routes that look ugly but climb well: left - The Fury - 11a - one star right - Climb With A Jew - 11b - one star
Upstream, on same side of canyon as Oasis, near Waterworld are two Argueso routes both about 11a/b, both one star.
