Look closely at the ground you will find evidence of the vast inland sea that once covered the Tumey Hills.
The light porous rocks are composed of diatoms, the tiny, bleached, shell-like skeletons of sea algae. Annual grasslands are lovely in springtime, with beautiful wildflower displays. Rarely seen federally-protected San Joaquin kit fox, blunt-nosed leopard lizard, and giant kangaroo rats make their homes in these hills. Visitors enjoy a day use facility with parking, shade structures, picnic benches, vault toilets and an interpretive kiosk with a map and information about the area.
