Forecaster note: This slide was spotted on Jan 27th (first photo below by J. Woodruff). It was not noticed on the 19th and maybe occurred sometime after that. The timing is uncertain.

Arm chair observation from the office in downtown Orem. Spotted this with the naked eye in the late afternoon (first photo). Photo is taken with a phone up to a binocular scope. I am guessing it started as a wet slide that then stepped down to a weak layer and then broke across the slope about a quarter mile wide. Estimating at least 5ft deep based off of how easy it is to spot. On the ridgeline just south of the north summit of Timp. Also saw some other wet slides on the south end of timp off of the cliffs (second photo). Similar wet slides also observed on the south end of Cascade (SW facing aspects) earlier this weekend. So it could be that the massive slide broke off a couple days ago.
