The Museum of the Earth is operated by the Paleontological Research Institution, affiliated with Cornell University, and covers 540 million years of Earth history with particular depth on the Devonian period: the same geological era whose shale layers are exposed in Ithaca's gorges and form the hillside soils along the wine trail. The museum explains why the Finger Lakes look the way they do: glacial advance, glacial retreat, the plunge pools and shale cuts that produced the gorge system. The 40-foot right whale skeleton in the main hall is one of the most complete in the country. The Cayuga Nature Center, with resident animals and exhibits on lake ecology and climate change, occupies an adjacent building. Open Thursday through Monday; admission charged.
