Yes, these are very common in dry areas where ranchers must construct stock
ponds.

fractal clusters of shallow rimless craters on lava plateaus -- result
of ice comet fragment air and surface bursts? very common in Great
Basin from Oregon to California: Rich Murray 2011.07.10

I readily found much more in 3 hours with Google Earth and Maps --
here are just two clusters -- may be evidence for fractal clusters of
air and surface
bursts of many ice comet fragments from typical gradual disruption of
a parent comet in solar orbit.

41.661806? -119.086891? 2.014 km el,
a shallow rimless crater, .6X.4 km,
16 m lower than 2.030 km plateau to S --
seems to be a lava surface,
with a number of similar craters.

fractal field of impacts on lava plateau,
one crater, about .6 km wide NW-SE
43.363764? -120.186009? 1.443 km el low,
23 m lower than 1.666 km edge to NE,
white and dark minerals on bottom,
N and E inner rim is darker.

The region is very interesting...
