The Soda Springs Hills are a small range located immediately northwest of Soda Springs. It includes both the Long Ridge and the Ninety Percent Range. This compact range is less than 7 miles long from north to south and less than 10 miles wide from east to west. It is separated from the Chesterfield Range in the north by Tenmile Pass and from the Bear River Range to the south by US-30 and the Bear River.
This is a low elevation, dry range with bare south- and west-facing slopes. As is common in this area, the east- and north-facing slopes are covered with conifer forests. The majority of the peaks in the Soda Hills are in the 6,000-foot range with one point – the range’s unnamed high point reaching to 7,024 feet. This peak is located on the main ridge of the range about 1.5 miles south of Tenmile Pass.
The Soda Springs Hills are a patchwork of BLM, private, and State lands. Much of the public lands are concentrated in the west and south end of the range. Hence, this is where the most easily accessible portions are. The eastern side of the range is mostly private, so access is limited. The main roads for accessing this are in Ninety Percent Canyon, Swenson Canyon and Idaho Ranch Canyon. There is also limited access from Tenmile Pass Road on the north and Government Dam Road on the east.
