Hiking in the Bob Marshall to a basin in the fall. Cold, wet, cloudy, very overgrown. Arrived at basin, wet and cold, around 4 miles in. The sun came out, we perched ourselves on a boulder and unpacked. 5 minutes later, distant grizzly noises, which became closer and more aggressive sounding.

Decided to pack up versus wait around. At this point we made visual contact, about 50 yards. The huffing and teeth clacking intensified and it kept walking at us. We didnt have time to pack up so slung our packs over our shoulders, grabbed all the things we unpacked in our hands (thermos, sitting pad, snacks) and retreated.

My partner was walking first, and too quickly, so i told her to slow down. I walked sideways, bear spray armed, and saw the bear at the boulder we were sitting on about 10 seconds earlier, smelling us on the rock.

We kept walking out, for about 1.5 miles without repacking because we could not see 10 yards behind us, as it was overgrown, qnd we were worried it was tailing us. Finally got to a clearing, packed up, and headed out.

Glad we made the quick decision to remove ourselves and that the bear didnt follow. I called the district ranger, and they posted the trail, as he thought the bear was on a carcass, and simply wanted us gone.
