Field Notes

Vesper and savannah sparrows sing from sagebrush perches. Mountain bluebirds fly over-head. A kestrel hovers over the open grasslands. A coyote hunts for ground squirrels and a mule deer steps from behind a rocky outcrop. In winter, elk descend from the Sapphire range to feed in the open bunchgrass and find shelter in the ponderosa pine draws. This is home, too, for the nonvenomous bull snake, as well as the western rattlesnake - watch your step!

Habitat Link

Native sagebrush is hard to find today in the Bitterroot Valley, mostly because of irrigation converting native grasslands to pasture and orchards. Fish, Wildlife & Parks manages this landscape to perpetuate the sagebrush and native grasslands that are important for elk and deer in winter, and for many grassland birds that are declining in the West because of loss of habitat, such as the Brewer's sparrow that depends on sagebrush.

Cultural Link

When the Lewis and Clark Expedition rode and walked through the Bitterroot, they saw the valley before the era of irrigation. As you explore this area, step back in time 200 years to when Clark described one of the challenges of walking through sagebrush grasslands in the Bitterroot - prickly pear.

"I observe great quantities of a peculiar Sort of Prickly peare grow in Clusters ovel & about the size of a Pigions egge with strong thorns which is So birded as to draw the Pear from the Cluster after penetrating our feet."

Viewing Tip

Pick up a trail map at the parking area and allow a couple hours or more to hike into the open foothills and up into the forests - open from April 15 to December 1. In winter, you can park and scan with binoculars in mornings or evenings to see elk.
