Michael Garrison > Cobbles of basalt, other volcanic and volcaniclastic rocks, and bleached coral form a long stretch of sandless beaches at Ukumehame, west Maui. These cobbles were transported to this and other beaches as alluvial and colluvial material that was produced by large swift-running streams cutting into the igneous rocks of the West Maui Mountains volcanic complex.

Michael Garrison > Looking southeast along the beach at Ukumehame, west Maui. The south Maui coastline is visible on the horizon. This and other beaches like it on this part of the island all share a western leeward exposure, so the prevailing winds are lighter. The smaller wavesets make these beaches popular with novice surfers and less-energetic bathers. The wide sandy beaches are relatively flat, stable, and free of high dunes, so weekend car and tent campers can set up close to the waterline.
