Neighborhoods along the Glenn Highway and Old Glenn Highway corridor are level or sloping, rising towards the Chugach Mountains east of the Old Glenn Highway. The remainder of the community lies along the canyon of the Eagle River; some neighborhoods built in the late 20th century and early 21st century near the Briggs Bridge are built very close to the bottom of the canyon. Neighborhoods along the northern portions of Eagle River, plus Hiland Road and Eagle River Road east of the curve where the road leaves the section line and descends into the canyon, mainly consist of houses built across the mountainsides. Wallace Mountain, on the far northeast corner of the community's road system, is home to several radio station transmitters and towers at the level.
