Abstract
The geological column in northern Utah has had very little detailed study. Those who have made reports on this section have done so only in a very general way, making no detailed sections of any part of the column, excepting that of the Cambrian made by Walcott.1 Other work has been done by Mansfield2 in southeastern Idaho and a general section of the Devonian made in Green Canyon, Bear River Range, Utah by Kindle.3
Due to the lack of any detailed work of this nature being done in the Bear River Range, suggested the matter of making a section and describing the Devonian System of this range, because, probably less is known of this system than of any other one.
Stratigraphic relations were studied in several sections where outcrops were good. Conditions for the study of these outcrops are very favorable, because, within a very short distance of 6 or 7 miles there are 6 canyons cutting the range at approximately right angles to the general trend of the structure, giving satisfactory sections of the greater part of the Paleozoic Era. Blacksmith Fork Canyon gives the best section of the Devonian System in the area studied. Because of easy access and good exposures, this canyon was chosen for a graphic section. Another section was made in Logan Canyon as a matter of comparison.
A - A is a general graphic section of the front range of the Bear River Range, showing the structure on the north side of Logan Canyon, situated almost directly east of the city of Logan, Utah./(Plate II) B - B is a general graphic section of the front ridge showing the structure on the north side of Blacksmith Fork Canyon. These graphic sections constitute the general lithological character of that portion of the Paleozoic Era which makes up this part of the Bear River Range. The eastern portion of the range is a faulted anticline and is capped, uncomformably, by Tertiary deposits.
