Observer Comments

Suspected glide cracks present on SW aspect of Cornbiscuit; see photos below! Visibility wasn't perfect, so add a forecaster note if any of these seem to have another explanation... but they all looked glide-like to me!
Glides in 12/24 Magnum observation (located in the Lynx Creek drainage) appeared the same today as 12/24.
