The pilot reported that he was landing the amateur-built, experimental airplane on runway 26 with the local winds reported as 260 degrees at 4 knots. He reported that as the airplane was touching down, the left wing came up and the right wing and nose wheel touched down on the runway at the same time. The right wingtip sustained substantial damage and the nose gear folded under the fuselage. The pilot reported there was a "valley on either side of the runway" which "funneled a crosswind" of greater velocity than the winds of the surrounding area.
