Sarkar cabin sits on a little peninsula in the lake. I flew over the lake several times and could not see it. When this happens I land and taxi around until I find it. I beached on the end of the point on some rocks and went ashore only to find a well protected mud beach on the south side of the point. Come in from the south of my way point and you should be able to see it, This is a standard Alaska cabin with a big covered deck and hidden in the trees. This lake has a few rocks which you can see from the air, use extra caution when maneuvering. Fishing is reported to be good, never have tried it.
