Eastern Mojave Vegetation Yucca Grove, San Bernardino County, California.

Query: G.N.I.S.

See also: Halloran Summit.

At the summit of the grade east of Baker on former U. S. Highways 91 and 466. Was on the north side of the highway at a location now called Halloran Summit. (U. S. G. S. 1956. Halloran Spring, California 15" quadrangle.)

Placed 1.2 miles west of Paso Alto (Halloran Summit) by California: A Guide to the Golden State (Federal Writers' Project, 1939), and described as follows, "(restaurant), is amid a grove of yucca trees. In the daytime the fantastic posturing of yucca limbs seems to mock the traveler. At night the dusky shadows of the contorted arms, backed by the star-crowded Mojave skies and the looming black bulks of hills, lend an air of deeper mystery to the desert."

There is a photograph of the motor court at Yucca Grove, taken in 1938, at: http://content.ci.pomona.ca.us/u?/Frasher,3530.

Elevation: 4131ft, 1259m.
