Description

I was very disappointed to find Western Poison Oak, and quite a lot of it, growing along the path on the north side of Lake Crescent at 580'. This was the first time I've found poison oak in Washington state.

poison oak is EVERYWHERE, it is probably the prettiest plant ever. This particular poison oak I found in the strebel homestead and it was right in the middle of the ruins of an old house.
