Abstract
Introduction
Twelve sections of upper Paleozoic to early Tertiary rocks from the Demarcation Point quadrangle and the northern edge of the Table Mountain quadrangle are presented. These measured sections include the type sections for the Joe Creek Member of the Echooka Formation (Section 11), the Bathtub Graywacke and Kongakut Formation (Section 9), and the unnamed early Tertiary rocks (Section 1). The early Tertiary rocks correlate closely with the Moose Channel Formation in the MacKenzie Delta, Candada (Detterman and Spicer, 1981).
The sections were measured with a Jacob's staff during the geologic investigations of the Demarcation Point quadrangle in 1969 to 1971. The geologic map is published in generalized form (Detterman, 1974, 1976; Detterman and others, 1975). The sections are at a scale of 1 in to 100 ft, except for section 1, which is at 1 in to 200 ft.
The location map shows the year and station number for each station. Fossils collected from these rocks and marked by and asterisk (*) are included in Detterman and others, 1975 (p. 42-45). A double asterisk (**) indicates they are included in the list below. All other fossil indicators mean fossils are present, but not collected.
