We decided to make the journey down to spanish fork peak today (just north of where highway 6 enters the spanish fork canyon heading for Price et al). The unexpected spindrifts evident as we drove down were indicative of what was to come. As we got up to the 8000 foot range the winds were honking from what seemed like the east and were loading the lee side of sub-ridges very fast. We were going up a shrub and log-free gully for a while but got out of it when we started getting small slabs cracking above us as we walked.
It turns out that we were following another party who thinks that they may have remotely triggered a pretty sizeable (1.5 footish) windslab that came off the lee side of a safe-ish sub-ridge that we were on, and what was unnerving was that it seemed like it was only about 30 degrees. After some time of getting sandblasted and being sketched by what we saw we decided to bail and descended on the windward side of our sub-ridge and even at that pulled out a small cross-loaded pocket. There was bigger stuff above us so we boogied out and were quite relieved to be down.
