Yes, this was interesting… he climbed up the boat ramp (sloped concrete) then walked about 20m up more concrete to an elevation here of about 5m above sea level. This is the landing area for the derrick pictured elsewhere in the photostream. A day after this photo was taken he was there again, with the swelling reduced considerably. I have seen him a couple of times since, and the flipper is very stiff, but he seems to be able to limp to where he wants to go. Today he was 1 of 2 California sea lions left on the jetty here.
