Observer Comments

Observed new glide releases on Seattle Ridge, S face of Wolverine, Cornbiscuit and in the Skookum drainage. Glide cracks appear to have grown in many locations.

I did not get a good photo of the Cornbiscuit glide cracks, however the looker's right released and the looker's left grew significantly since Sunday.
