Mile 1866.0 to 1889.3 for 23.3 miles. Camp was at Summit Lake at an elevation of 5582 feet. Our elevation gain was 3064 feet and loss was 3691. We were hiking at 6:45 and into camp at 5:45. The morning was chilly and the slightly smoky skies got better as the day progressed. Jerry had hurt his ankle descending from Rim Village (Crater Lake) and it is now swollen. We had very few Advil but were fortunate to find some at a water cache. Sometimes st caches there are hiker boxes with supplies for hikers to take if they have a need. I was also able to get some Advil for my knees that have been acting up. The best thing at this cache was a fuel canister with enough fuel to boil a liter of water. We both had a hot meal in addition to our lunch. We had a lot more energy afterwards. The trail was mostly in timber and of great quality. We are ahead of schedule so ate another one of our lunches for dinner. Yellow jackets continue to swarm us at breaks. This has been a constant since Ashland, Oregon and we are not sure what they want. They just seem curious about us and our gear, but they’ll fly within an inch of us as we sit. Jerry was lectured from another hiker for giving a pecan to a chippy, but the same hiker was sealing up her zip lock bag with the bees inside; hence killing them. Go figure. Several PCT hikers chose a shorter alternate route that saved them 8 miles on the way to Shelter Cove.
