The Earth Sciences Collections contains more than 500 geological and paleontological specimens from around Kachemak Bay and the surrounding region.
This collection includes bison and woolly mammoth fossils,a rare fossil imprint of a local perch, glacial erratics carried to Homer beaches, and a collection of fossil mollusks representing the diverse, prolific life of our ancient seas. The collection includes vertebrate and invertebrate fossils from various locations in South Central Alaska.
The Pratt houses numerous geological samples and specimens from our region, including a collection of volcanic ash samples, pumice, and lava bombs representing active regional volcanic activity.
The biological collections at the Pratt consist of 2,500 regional specimens and objects. A marine life collection represents a baseline study of marine plants and animals (wet-preserved) and drift/beach materials (dry-preserved) of Kachemak Bay. There are thirty mounts of marine and freshwater fish featuring common species of Kachemak Bay. There are over 500 mounts, study skins, skeletons, and nests of birds, representing a wide range of bird and mammal species in Alaska, including a collection of 30 salvaged marine mammals, pre
pared largely as articulated skeletons. One particularly unusual specimen is the massive rib of an extinct Steller’s Sea Cow from Bering Island.
The Pratt’s Herbarium, housed within Natural History Collections storage, contains a collection of over 1,200 specimens, and represents 347 species of plants from around Kachemak Bay and remote, offshore islands.
