Not illustrated. 1904 Excerpt: ...notably on the south side of the Anaktuvuk, the Lisburne is cut by a close jointing, trending N. 27 E., with dip southeast-east at an angle of 85, dividing the rocks into thin slices from 2 to 8 inches in thickness. There can be but little doubt that the faulting between the Lisburne and the Fickett series continues eastward and connects with that along the southern edge of the Bettles series, on Koyukuk and Chandlar rivers. Its alignment with the boundary of the Bettles series, as located in a previous year's work," is shown on the geologic map, PI. III. Age.--The most convenient disposition to make of the Lisburne formation would be to include it with the Fickett series and call the group Carboniferous and Devonian, since both Carboniferous and Devonian fossils occur freely in the stream gravels of the upper John and Anaktuvuk rivei's, and none of the fossils found in place were sufficiently well preserved for identification. On lithologic grounds, however, the Lisburne formation can be set apart as qu;te distinct from the Fickett series, which it also seems to underlie. Therefore, on the basis of the Devonian fossils found in detached fragments of rock on the surface of the formation near the top of the mountains, and on the lithologic similarity of the rock attached to these fossils to that of the Lisburne formation, the formation is provisionally referred to the Devonian.
