Fig. 2. — Interbedded basalt flows in the Rosamond series, north flank of the El Paso 

 Range. The northwestward dipping strata of the north flank are shown, and also the strike 

 valleys excavated between the hogbacks of more resistant rock. On the lower slopes in the 

 middle distance is a terrace of horizontally bedded alluvium. The high peak on the middle 

 of the horizon is Black Mountain, separated by a depression from the main granite range 

 on the right.
