The old county road between Wolf Creek and Grave Creek on the Pacific Highway in Northern Josephine County, passed over two summits about 250 feet above the valley levels of Grave and Wolf Creeks, giving four long, heavy grades, in some places the grade being as high as 25 per cent. These two summits were about one mile apart, and the nature of the ground was such that support could be had for a practically level grade between the two.
With a view to locating this level grade between the summits and developing five per cent grades down the sides, a preliminary survey was made in October and November, 1916, under the direction of Mr. S. H. Probert. This survey was worked up in the office during January and February, 1917, and in July, 1917, the projected location was staked on the ground by Mr. C. C. Kelley, locating engineer.
The length of the survey was 4.9 miles, the terminal points being about three-quarters of a mile east of Wolf Creek Post Office and about three-quarters of a mile west of the Grave Creek Bridge.
The construction of this section, which was undertaken in the fall of 1917, is described in another article in this report.
Survey—Wolf Creek to Stage Road Pass
ON THE WOLF CREEK-GRAVE CREEK SECTION OF THE PACIFIC HIGHWAY
IN JOSEPHINE COUNTY. GRADED IN 1918
This survey begins about three-quarters of a mile south of the Wolf Creek Post Office and follows, in a general way, the present county roads into the town of Wolf Creek and from Wolf Creek to a point about two miles south of Stage Road Pass. At this point it connects with a survey made by the Highway Department in 1915, and which is the location survey for a five per cent grade down from State Road Pass, which pass is on the line between Douglas and Josephine Counties.
The length of the survey from east of Wolf Creek to the connection with the previous survey is 2.5 miles. It was made in July, 1917, under the direction of Mr. C. C. Kelley, locating engineer.
