Fig 3. Lake Kauhako. A) Cross section of Lake Kauhako, showing a vertical profile of the lake basin, and the lake’s location on the Kalaupapa Peninsula on the north shore of Moloka‘i. B) A view of the Kalaupapa Peninsula from the 2000 ft. sea cliffs that flank the peninsula’s south side and effectively isolate it from the rest of Moloka‘i. The only way to the peninsula is down a cliff trail, by air, or by sea. No roads join the area to the rest of the island. C) Lake Kauhako sits in the bottom of a densely wooded crater. D) In some places the trail is steep and can only be negotiated by rope. The terrain makes sampling difficult because everything has to be carried in and out from the top of the 400 ft deep crater. It’s also easy to get lost in the dense bush. [back]
