From email: "My partner and I were out ice climbing in Hyalite today and I wanted to share our observations.
Our objective was Cleopatra’s needle. We arrived at the base of the climb around 11:30, skies were clear and winds were calm. Once I topped out around 3:30pm, skies were overcast and winds were picking up from the northwest and began to transport snow off the trees. I also noticed a pretty sizable crown on one of the convexities above Twin Falls. I traversed around to get a better look and took a couple pictures.
The crown appeared very new, likely within the past couple of days I would guess. It appeared 3 feet at its deepest and roughly 100 feet wide. I’m not sure if it was a natural or remote trigger, but definitely a scare nonetheless for any potential climbers below."
