Here is a brief excerpt:
The legislation, introduced last month by Rep. Jim Costa, D-Fresno, authorizes the National Park Service to expand Yosemite's western boundary through the addition of several adjacent Mariposa County parcels. The park service could buy the designated land, located near an existing resort development called Yosemite West; in theory, the agency also could accept donated property or acquire it through a land swap.
The Pacific Forest Trust currently owns about half of the 1,575 acres covered by the bill, and a consortium of medical professionals owns the other half. The nonprofit trust bought its share about seven years ago with the long-term goal of conveying it to Yosemite, Wayburn said. The doctors had bought the land as an
investment, potentially for development.
