Rh only be inferred from the topographical features existing in the gap.

This township lies immediately south of White Deer, with the Susquehanna river for its eastern boundary, Buffalo creek for its southern border line, and Spruce run on the west. The nearly straight southern line of White Deer township, 6 miles long, between Spruce run and the river, is a mutual north line of Kelly township. The area embraced between these lines approximates 15 square miles.

The drainage is all eastward through Buffalo creek to the river, the main creek receiving the waters of Little Buffalo creek about 3 miles from the river and Spruce run at a distance of 6 miles, both of which streams rise in the mountain area of White Deer township and flow southwards into Buffalo creek.

West Milton, in the extreme northeast corner, on the river and Philadelphia and Reading R. R., is the only village of importance, and is practically a suburb of the larger town of Milton, on the east side of the river, in Northumberland county.

The Milton anticlinal axis of that county reaches the Susquehanna river just below Catawissa Junction, and carries a narrow strip of the upper Clinton brownish lime shales on its crest for about 5 miles west of the river, where the Bloomsburg red shale or lower Salina rocks fold over the expiring western end of the axis, which cannot be traced beyond Spruce run.

The Jones mountain anticlinal, or the northern sub-axis of the Penns Valley anticlinal of Centre county, expires coming eastward just beyond Spruce run in this township, where its crest is dimpled with a double fold of the upper Clinton rocks, with a little of the Bloomsburg red shale caught in the narrow synclinal crimple between them.

The Lewisburg synclinal, corresponding to the Lackawanna basin of Northumberland county, just touches the southern border of this township along Buffalo creek, where it holds an elliptical area of the Marcellus black slate nearly
