Boise is at about 2700 feet and not far to the north, NE. and East are shallow mountains that rise above the plateau. Looking at my atlas, I would say the Boise is only about 6 - 8 miles from elevations of 5000 feet.

A good number of years ago either on this forum or another herp forum was a gentlemen that mentioned he found Rubber Boas by night driving back dirt roads in sagebrush county somewhere near Boise. It would be my guess that the locality of his finds were NE and east of Boise proper.

Remember that in order to increase your chances of finding the species during your hiking, you need to find rock outcrops and / or talus in order to search beneath those rocks.

If you send me a private message, I can tell you exactly where I found the species along I-84 but it is a considerable distance from Boise.
