In a previous post, I wrote about the local legend of observable snow on Mary’s Peak on or after June 1. Twice in recent years (1999 and 2008), snow has been visible from Corvallis in June.
On June 3, 2011, I took the following photos from southwest Corvallis:
Mary’s Peak from Country Club Road near 53rd Street
Mary’s Peak, same location as previous photo, zoomed in
Mary’s Peak, zoomed in further
Yep, it happened! Snow on Mary’s Peak visible from Corvallis!

I wonder if there is still snow in pockets today? On the NW side maybe?
It wouldn’t surprise me. There was a LOT the last time I was there!
