The site is apparently geologically unique in the Hawaiian Islands, comprising a sinkhole paleolake in a cave formed in eolianite limestone. The paleolake contains nearly 10,000 years of sedimentary record; since the discovery of Makauwahi as a fossil site, excavations have found pollen, seeds, diatoms, invertebrate shells, and Polynesian artifacts, as well as thousands of bird and fish bones.
Kazumura Cave hosts a number of endemic cave arthropods found only on the island of Hawai'i, including a blind planthopper which feeds on the roots of native ʻōhiʻa trees (Oliarus polyphemus), a cave cricket (Caconemobius varius), a millipede, two species of Schrankia moths, an earwig, several species of spiders, and a unique cave-adapted water treader (Cavaticovelia aaa).

A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors (subtroglophiles and trogloxenes).

The island is the top of a volcanic tuff cone that rests on top of a larger, submerged shield volcano. At its highest point, the island reaches a height of 548 ft (167 m). [1] The ocean has carved large sea cliffs on the sides of the island. There is a large cave on the northwest side of the island called Kahalauaola (Shark Cave). [2]
Nihoa (/ n iː ˈ h oʊ. ə /; Hawaiian: Nīhoa [niːˈhowə] or Hawaiian: Nihoa), also known as Bird Island or Moku Manu, is the tallest of ten islands and atolls in the uninhabited Northwestern Hawaiian Islands (NWHI). The island is located at the southern end of the NWHI chain, 296 km (160 nmi) southeast of Necker Island.
Located about 2,300 miles (3,680 km) from the nearest continental shore, the Hawaiian Islands are the most isolated group of islands on the planet. The plant and animal life of the Hawaiian archipelago is the result of early, very infrequent colonizations of arriving species and the slow evolution of those species—in isolation from the rest of the world's flora and fauna—over a period of ...

It was once connected to the island of Maui Nui before splitting off about 300,000 years ago. Most of the island is covered by basaltic lava flows. A caldera is located in the eastern part of the island. The last confirmed volcanic activity on the island occurred about one million years ago, though eruptions could have occurred about 10,000 ...
