Residual corestones (10-20 cm in diameter) formed by mineralization of cracks and joints in deeply-weathered trachyte lava. The Dragon's Teeth, Makaluapuna Point, near Kapalua, west Maui.
One of the "teeth" of The Dragon's Teeth at Makaluapuna Point, near Kapalua, west Maui. The nearly overturned surface feature of the old lava flow displays mineralized polygonal joint networks (cracks) and laterite concretions (cannonball-like structures inside the polygons), both of which are indicative of advanced chemical weathering at work.

Evidence of physical weathering at work on the trachyte lava of The Dragon's Teeth, at Makaluapuna Point near Kapalua, west Maui.
Weathered surfaces of a lava flow at the Dragon's Teeth, Makaluapuna Point, near Kapalua, west Maui. 

Physical weathering (in the form of wave action and precipitation) has caused "pitting" on the old flow surface and widened the joints and chill cracks.
Looking back landward along Makaluapuna Point toward the main building of the Ritz-Carlton Hotel and Flemming State Beach. Clouds obsure the crest of the West Maui Mountains in the background. The boulder-strewn beach (right middle ground of photo) is covered with coral debris (many fragments have interesting shapes and coloration) and flotsam and jetsam washed ashore during storms and tidal high stands. The brush-covered slope (right middle ground of photo) conceals the remains of the more than 2,000 Hawaiians interred in the old burial grounds. Their mana is strong here and can be felt as well as seen, most strikingly in the unusual beauty of the landscape.
