I tried some recon today at 4000-5000 feet in Arnold. Area in the OHV area is devastated, Top of the ridges must have had gnarly winds. Fields of 100+ tall trees whipped out. There ere hundreds of these 100+ foot trees which collapased. They seemed to be affected by the bark beetle. All trees appeared to collapsed without the benefit from a chain saw and fell at 2-4 feet of base. Forests are going to be messed up from winter. Worst I have seen it. Ride added an additional 1.5 hours to hike around debris field.
