depressed area

The posterior portion has a slightly depressed area (see fig. 5B) at the junction of the "arms" of the Y.

Typically, they contain a basin-shaped depressed area that is surrounded by a rim.

At an early period this depressed area drained southward to the Colorado, and the bed of the old outlet can still be traced.

In the depressed area beneath the archway, surface water had failed to run off.

The circular depressed area was doubtless used as an Estufa, the place of religious meetings for men alone.
