Original description: ibid.

The name Monay Boulder Beds was assigned by A. Salvador (1950) to boulder beds that outcrop just east of the Llanos de Monay in northern Trujillo.

The formation (Salvador, 1950) is composed of beds of unconsolidated, large, rourded boulders of quartzitie sandstone. The boulders are 30 to 73 centimeters in diameter, coated by brown, ferruginous material, and were deposited without any apparent bedding. The thickness of the beds is unknown but it is probably extremely variable. These beds probably underlie a large part of the Llanos de Monay.

The Monay boulder beds probably overlie the older formations unconformably and are overlain unconformably by river terraces. The age was tentatively assumed to be Pleistocene.
