Notes

From an email:

"...ski cut this little 100' convex roll slope that is 35 degrees for its majority.  It slid as expected. ESE facing @ 7500' prominent wind loading from SW.  Did not step down through the harder wind crusts.  1-2' deep and 50' wide, ran 100'.  Storm snow was getting very upside-down with moderate SW heavily loading E aspects."
