Changes in the terrestrial ecosystems of islands have also been noticed during the Holocene period. Studies (high resolution & Total Inorganic Carbon) and records of Lake Pyramid and Lake Owens show that 5 distinct climatic episodes – cool period followed by a dry period (11.6 – 10 ka) interspersed with a wet episode predominated the early Holocene period. The latter part of the early Holocene (10-8 ka) was mostly wet resulting in a substantial body of water in Lake Owens and movement of water from Lake Tahoe to Lake Pyramid.
