Lost River (Bering Sea)
Lost River is a waterway on the Seward Peninsula of the U.S. state of Alaska. Rising in the York Mountains, the river empties into the Bering Sea, west of Port Clarence. It is located east of Cape York.
==Geography==
Lost River has a length of about , and drains the central part of the York Mountains. Its two tributaries, Tin Creek and Cassiterite Creek, enter from the east about and , respectively, from its mouth, and tin ore has been found on both of these creeks. Cassiterite Creek, which is really the larger fork of Lost River, has a length of about . Tin Creek, about long, heads within about of Cassiterite Creek, and, flowing parallel with it for about the same distance, turns westward and enters Lost River through a canyon cut in the limestones of the York Mountains. Lost River itself flows in a comparatively broad valley cut in these limestones. The bed of the river is not deeply gravel filled, and the valley floor is practically cut out of the limestones and not to any extent built on them. The mouth of Cassiterite Creek is about above the sea. Between Tin Creek aad Lost River, there is a stock of granite intruded into the limestone, which outcrops in a nearly circular area, probably in diameter.
