I skipped work yesterday (Thursday 2/6) and headed down to Index. I took ScottP's advice and did the first 2 pitches of The Zipper and the first 3 of Dana's Arch.
The Zipper was awesome. Strenuous exposed moves out a huge roof. There is a lot of fixed gear along with some interesting camhooks and micronuts at the lip. I blew a pin (5/8 angle) while cleaning so it either needs to be replaced or bring some aliens. Definitely a bit harder than anything on GD or TC.
Dana's Arch was excellent as well. Sustained, tricky aid throughout. I left narrow and wide camhooks on each daisy and used them over and over again. The first two pitches link and have lots of manky bolts and weird hooking to keep things interesting, maybe...C2+? At one point you hook a large pocket lined with quartz crystals, never seen anything like it.
The third pitch was bit harder. Lots of bat hooks, hooks, mediocre cams and more manky bolts. I blew a chunk of rock out using a micro camhook resulting in a daisy fall on a bathook (IT HELD!). So I fixed a pin in the resulting scar. Pitch is probably C3, though bring a few skinny pins just in case.
Both climbs don't need any gear bigger than 2 inches. Camhooks seem mandatory. For Dana's Arch bring 2 bathooks, 1 skyhook and 1 fishhook. Fun! Fun! Didn't see a soul all day.
