Nice video. Russian lake is on my "to do" list for this year, as is Upper Gull Lake- plus maybe a trip to Andy's Creek (or as the sign calls it, "Andes Creek"). Would be nice if I can get 3 consecutive nights to camp in all 3 spots in a single trip.
I
visited Lower Sister Lake with a friend for a 1 night trip back in 2013. Definitely a neat area. I think the combination of having to paddle (or at the least, take a boat) and then hike several miles to camp keeps the use level for Lower Sister Lake pretty low. Not sure about the other lean-tos as they are shorter hikes- so maybe they get a little bit more use.
