Describe Sutter Buttes Park Access here. The California State Park land in the Sutter Buttes sits across a road that appears on federal General Land Office surveys and maps while the land was still a part of the public domain. This by itself is a strong argument that the park land are accessible by public road at this time. Copies of federal land survey plats and field notes are at the Sutter County Public Works office. The rationale is discussed in Western Aggregates v. County of Yuba, the third district court of appeal case that opened up the Marigold to Brown's Valley road.
