FOUNDATION
The Hayden Gulch site lies within the Williams Fork Mountains at
the southern edge of the Wyoming Basin physiographic province
and immediately north of the White River Plateau, a westward ex-
tension of the Southern Rocky Mountain province.
With regard to major tectonic units, the Hayden Gulch area is
located in the structural limb separating the Sand Wash 8asirt to
• the north and the White River Uplift to the south. The site is
situated on the southwestern limb of the small, Northwest plung-
ing Watering Trough sync]ine. Strata in the immediate area dip
4 to 8 degrees northeast.
All bedrock exposed in the Hayden Gulch area is Upper Creta-
ceous. The youngest is the Lewis Shale, followed by the
Williams Fork and Iles formations of the Mesa Verde group, and
the Mancos shale.
For further information refer to Volume I, Section 2.04.6, geo-
logy description.
