- Interstate 90 tends to form the southern boundary of this conservation area. However, there is a short segments in which the highway is entirely contained in the conservation area. The same occurs with the western border with the Middle Fork Snoqualmie River. The river tends to define the border, but at points may be contained entirely in the conservation area. It is not clear whether this is intentional or a result of the meandering river.
- Middle Fork Snoqualmie Natural Resources Conservation Area (dnr.wa.gov)
The Middle Fork Snoqualmie Natural Resources Conservation Area (NRCA) was established in 2011 with the transfer of 9,224 acres from DNR-managed state trust lands into conservation status. Today, the NRCA is 9,198 acres. The NRCA abuts Mount Si NRCA to create a large forested landscape from the North Bend to the Mount Baker-Snoqualmie National Forest- extending from 800 feet elevation at the Middle Fork Snoqualmie River to 5,000 feet. This conservation landscape protects wildlife habitat, scenic views, and the upper reaches of the river while also offering low-impact recreation on a variety of hiking trails.
