The is the entry from my book for February 12, 1875: "President Grant established the Lemhi Valley Indian Reservation in central Idaho. This act was instigated by the effort of Chief Tendoy and his Lemhi followers."
This is Lemhi Pass (7,373 feet high). The road at this point is little more than a jeep trail. It eventually goes to Grant, Montana. From the Lewis & Clark journal: "They left reluctantly this interesting spot, and pursuing the Indian road through the interval of the hills, arrived at the top of a ridge, from which they saw high mountains, partially covered with snow, still to the west of them. The ridge on which they stood formed the dividing line between the waters of the Atlantic and Pacific oceans."
This is both sides of the same sign.
The Idaho side...
The Sacajawea (yeah, I know, the spelling changes from place to place) monument is located at the top of this hill. There is snow & ice everywhere.
The only significance of this picture is that it was taken after 9pm. It was still light out. I suddenly remembered how far north I was. This was at the Gilmore Summit on Highway 28 around 7,186 feet.
