Day 4- We were up early and packed up camp. Breakfast was breakfast burritos and coffee. The plan was to find a site north of the burn area on Lake Four. This was our toughest day paddling. With a strong headwind and multiple portages, we made our way back from Insula to Hudson and then Lake Four. Our preferred sites (1483, 1484) were both occupied and we were getting a little worried. We paddled further west and found the last site (#1485). This site is up on a hill and had a flat camping pad but the kitchen and fire grate were on a slope. Did some fishing after setting up camp with minimal success. Dinner was cheese and shells with spam. The weather was low 70's and partly cloudy during day. This was the coolest of the nights dropping into mid 40's overnight.
