Location
"Hers" in Grotto Canyon

Lots of evidence of recent rock fall from the loose, chossy roof from which the ice climb known as "Hers" seeps, including one particularly large microwave-sized block laying on the ground at its base (see photo). I did not witness this rockfall event, but it is clear that it was fairly new; most likely in the past 24 hours with the very warm temperatures that we are currently experiencing (above zero Celsius). This roof that overhangs "Hers" has become notorious in the past year for shedding. Last winter in mid-March (2020), I witnessed a toaster-sized rock fall from the roof on a warm day and hit a climber in the arm while they were climbing. It would be best to avoid climbing "Hers" until cold temperatures freeze the rock in place, and still be super aware and ready to bail if the temperature increases or when the midday sun hits the route.
