Abstract
The Howell Creek Structure -- A Paleogene Rock Slide in the Southern Canadian Rocky Mountains
ABSTRACT
The Howell Creek structure exposes an area of Upper Cretaceous sandstones and shales surrounded by Paleozoic limestones in the southern Canadian Rocky Mountains. Since its discovery, the structure has become widely known as a tectonic window in which the usual relationships between overthrust and subthrust strata have been modified by later faulting. Recent road works and a forest fire have created new exposures which show that the Howell Creek structure is an ancient rock slide, emplaced during or shortly after the phase of extension faulting that followed the early Tertiary deformation of the Front Ranges of the Rocky Mountains.
