Trip Report: Mt. Timpanogos, UT โ โGrunge Couloirโ Yesterday, May 26th, 2020, I walked, bushwhacked, and crampon-ed my way up the legendary โGrunge Couloirโ of Mt. Timpanogos in Utah. Iโd be lying if I said Iโd slept great the night before skiing this thing. I was scared of the constant rockfall, of the ice in the chute, of the steepness at the top, and of the 62ยบ no-fall-zone [โฆ] Trip Report Miles Clark | May 28, 2020 7 Comments
