In 1917 a location survey was made from the Grant-Wheeler County Lines
east of Spray to Valades Ranch, five miles west of Dayville. The line
crosses the North Fork of the John Day River at Kimberly's Ranch and
follows up the Big Basin Valley along the east bank of the John Day
River. A crossing is made near the upper end of Big Basin and the line
follows the west bank of the river through Picture Gorge Canyon. On
leaving Picture Gorge the line enters the John Day Valley, and continues
on the west side of the river to Valades Ranch where the project ends.
Valades Ranch is five miles west of Dayville. This is a portion of the
Sarvice Creek-Valades Ranch Post Road Project and the Grant County
section is twenty-three and forty-five hundredths miles in length. This
survey was made under the direction of R. H. Coppock, locating engineer.
