This flow only comes in during really cold spells. The route gets sun, especially on the top half. The name comes from the quality of ice on the top during a warmer day and the intelligence of the F.A. party (for leading it). The flow is normally thin, with easy mixed sections of blank rock.
Location
This flow can be seen looking east at the top of the Black ridge while driving on I-15. (approximately mile #37-38) If you can't see it, it's not in. Park at the exit #36 off ramp or pull off after the gaurd rail at the top of the ridge while traveling north on I-15. There is a dirt road. 15 minutes of hiking will get you to this flow.
Protection
Screws and possibly creative rock craft. Leading during lean conditions is not recommended (R/X). Two bolt anchor at top.
