Description of Snow, Weather, and Avalanche Conditions: 

I observed an avalanche up above Whites Creek. I took a picture from my house, which is 5 mi away as the crow flies, and it did not turn out well, thus this short narrative.

There was a secondary slide next to the main one 50' away climbers right with the starting zone at about 8600', which had the same terminus as the main one. The terminus was behind another ridge, but I could tell it ended toward the bottom part of the runout zone.

It was filled in a bit, so I assume it was from a couple of days ago.

Sorry for the vagueness; it was the best I could do at 5 miles away!
