Lake Modoc

Lake Modoc was so named by Samuel N. Dicken, professor of geography at the University of Oregon.

It covered a length of 120 kilometres (75 mi) from south of Tule Lake in California to near present-day Fort Klamath in Oregon, its waters reaching an elevation of about 1,292 metres (4,239 ft) above sea level and covering an area of about 2,839 square kilometres (1,096 sq mi)[1] with a highly irregular shape.

[1] Lake Modoc also featured an outflow,[1] at first to the south before a lava flow blocked it,[4] although seepage continued from there to this day.

[10] Water levels began to decrease as the Pleistocene ended,[2] as the climate became drier and the outlet to the Klamath River lower.

[1] The floor of the drying lake featured deep soils and abundant vegetation, water and wildlife; thus it was quickly populated by humans who migrated there over 3,000 years ago.
