Thornton Lakes

Trappers Peak is a 5,966-foot (1,818 m) elevation mountain summit located in the North Cascades of Washington state. It is situated within North Cascades National Park, Stephen Mather Wilderness, and Whatcom County. It rises steeply above Lower Thornton Lake which is set at the southwestern face of the mountain. Like many North Cascades peaks, Trappers Peak is more notable for its large, steep rise above local terrain than for its absolute elevation. Topographic relief is significant as the southeast aspect rises 5,500 feet (1,700 m) above the North Cascades Highway in approximately two miles. The nearest higher neighbor is Thornton Peak, 1.5 miles (2.4 km) to the northwest, Mount Triumph is two miles to the northwest, and Newhalem is three miles to the east-southeast. Precipitation runoff from the mountain drains into tributaries of the Skagit River. The summit of Trappers Peak is known for its grand view of the jagged peaks of the Picket Range.

Mount Triumph is a summit in the North Cascades range of Washington state. Located approximately 5.5 miles (8.9 km) west-northwest of the town of Newhalem, it was named by Lage Wernstedt, a surveyor with the U.S. Forest Service. A significant peak in North Cascades National Park, Mount Triumph is one of its "outstanding sights" and is well known among regional climbers for its lack of easy climbing routes to the summit. Despite its moderate elevation, its local relief is dramatic. With the terrain deeply dissected by the valleys of Bacon Creek on the west and Goodell Creek on the east, it rises 1 mile (1.6 km) in less than 2 miles (3.2 km) on the latter side. The mountain is extremely rugged and one author describes it as "a rock thumb with near-vertical to overhanging faces on three sides." From above, it has the appearance of a three-bladed propeller consisting of the northeast, northwest, and south ridges. Mount Despair (7,292 ft or 2,223 m) is located 2.3 miles (3.7 km) to the north-northwest. The two peaks are connected by Triumph Pass (5,520 ft or 1,680 m).

Damnation Peak is a 5,635-foot-elevation (1,718 m) mountain summit located in the North Cascades of Washington state. It is situated within North Cascades National Park, Stephen Mather Wilderness, and Whatcom County. Like many North Cascades peaks, Damnation Peak is more notable for its large, steep rise above local terrain than for its absolute elevation. Topographic relief is significant as the south aspect rises 2,800 feet (850 meters) above Damnation Creek in approximately 1.5 mile, and the north aspect rises 3,000 feet (910 meters) above Triumph Creek in one mile. Precipitation runoff from the mountain drains into these tributaries of the Skagit River. Neighbors include Mount Triumph, 2.8 miles (4.5 km) to the north-northeast, and Trappers Peak is 2.8 miles (4.5 km) to the east-northeast. The town of Newhalem is six miles to the east. In 1938, Lloyd Anderson climbed a nearby summit which is known today as Thornton Peak and called it "Damnation."

Mount Despair is a rugged mountain in the North Unit of North Cascades National Park in Washington state. Northeast of Mount Despair lies the Picket Range. The mountain's name was given by Lage Wernstedt of the U.S. Forest Service who mapped the region in the 1920s. The name Mount Despair first appeared on Forest Service maps in 1931.

Goodell Creek is a tributary of the Skagit River in the U.S. state of Washington.

The Chopping Block is a 6,819-foot (2,078-metre) mountain summit located in the Picket Range within North Cascades National Park in the state of Washington. The mountain is officially named Pinnacle Peak on maps, but hardly anyone calls it by that name. The nearest higher peak is Mount Degenhardt, 0.6 mi (0.97 km) to the northeast. The Chopping Block can be seen from the North Cascades National Park Newhalem visitor center, weather permitting. Precipitation runoff from the peak drains into Goodell Creek, a tributary of the Skagit River.

Newhalem (Lushootseed: dxʷʔiyb) is a small unincorporated community on the Skagit River in the western foothills of the North Cascades, in Whatcom County, northwestern Washington, United States.

Ross Lake National Recreation Area is a US national recreation area in north central Washington just south of the Canada–US border. It is the most accessible part of the North Cascades National Park Complex which also includes North Cascades National Park and Lake Chelan National Recreation Area. Ross Lake NRA follows the Skagit River corridor from the Canada–US border to the western foothills of the Cascades. The NRA contains a portion of scenic Washington State Route 20, the North Cascades Highway, and includes three reservoirs: 12,000-acre (4,900 ha) Ross Lake, 910-acre (370 ha) Diablo Lake, and 210-acre (85 ha) Gorge Lake. These reservoirs make up the Skagit River Hydroelectric Project operated by Seattle City Light. Nestled in the "American Alps" the Ross Lake NRA bisects the north and south units of North Cascades National Park.

The Roost is a 6,705 ft summit in the Picket Range which is a sub-range of the North Cascades Range of Washington state, United States. It is located within North Cascades National Park and Stephen Mather Wilderness, and is situated one mile north of Mount Ross. Like many North Cascades peaks, The Roost is more notable for its large, steep rise above local terrain than for its absolute elevation. The Roost was first climbed on July 12, 1966 by John and Taffy Roper. The nearest higher neighbor is Glee Peak, 1.76 miles (2.83 km) to the north. Precipitation runoff from the mountain drains into the Skagit River.

Mount Ross is a 6,052-foot (1,845 m) mountain summit located in the North Cascades, in Whatcom County, Washington, United States.

Big Devil Peak is a 7,055-foot-elevation (2,150 meter) mountain summit located in North Cascades National Park in Skagit County of Washington state. The peak lies midway between Marblemount and Newhalem and can be seen from the North Cascades Highway at the road pullout for Big Devil Falls. The peak rises 6,600+ feet above the valley floor at this viewing location in the valley. Big Devil is the highest peak of Teebone Ridge, and other peaks on this ridge include Little Devil Peak, Fallen Angel, and The Trapezoid. Precipitation runoff from the mountain drains into tributaries of the Skagit River.

Gorge Dam is one of three along the upper Skagit River in Whatcom County, Washington, and part of the Skagit River Hydroelectric Project that supplies Seattle with some of its power needs. Construction on the original wooden Gorge Dam began in 1921, with its generators formally started by President Calvin Coolidge on September 17, 1924. In 1961, a new Gorge High Dam, made of concrete, was completed to replace the original.A pivotal scene in the 1974 Warren Beatty film, The Parallax View, was shot at this location. In 2020, the Upper Skagit Indian Tribe created an online petition calling for the removal of the Gorge Dam.
