About this map

Orestimba Peak rises as a prominent landmark within the eastern reaches of the Diablo Range, where the steep topography of the coastal mountains meets the western edge of the San Joaquin Valley. This 2018 survey detail provides a clear look at the drainage systems that define this terrain, most notably the winding path of Orestimba Cr as it flows toward the Central Valley.

Land use and access are dictated by the rugged contours, with Orestimba Rd navigating the lower elevations near Orestimba Narrows and Bennett Valley. Higher elevations to the south and west are punctuated by Black Mtn and Crow Hill, while water management is visible through features like the Merriam Drain. This modern topographical study captures the transition from the arid uplands of the Diablo Range to the fertile valley floors, preserving the specific hydrology of Crow Cr and Oat Gulch.
