Question: What park are both Marias Pass and Summit Mountain around?
Context: Summit Mountain (8770 ft ) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.  Summit Mountain towers to the north of Marias Pass and is situated along the Continental Divide. Little Dog Mountain (8610 ft ) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.  Little Dog Mountain sits along the Continental Divide and can be easily seen from Marias Pass. Marias Pass (el.  5213 ft/1589 m) is a high mountain pass near Glacier National Park in northwestern Montana in the United States. Pigeon Pass Valley, is a valley in Riverside County, California.  Its mouth lies at an elevation of 1696 feet / 517 meters above Poorman Reservoir.  Its head lies on the south slope of the northwest extreme of the ridge of Reche Summit mountain at , northeast of Pigeon Pass. Three Bears Lake is located in Glacier National Park, in the U. S. state of Montana.  The lake is adjacent to the Continental Divide and .5 mi northwest of Marias Pass. Green Lake is located in Glacier National Park, in the U. S. state of Montana.  The lake is near the southern border of Glacier National Park, midway between Marias Pass and East Glacier Park, Montana. McGregor Pass, 1555 m , is a mountain pass located on the Continental Divide in the Canadian Rockies and near the head of the McGregor River, to the north of Wishaw Mountain and to the west of Kakwa Pass, which is in the same vicinity.  McGregor Pass forms the division between the Hart Ranges of the Rockies, which begin at Mount Sir Alexander just to the northwest and extend to the Peace Reach of Lake Williston, and the Continental Ranges, the largest and most well-known segment of the Canadian Rockies, which extend to Marias Pass, at the head of the North Fork Flathead River in Montana, United States. Essex is an unincorporated community in Flathead County, Montana, United States.  Located in the northwestern part of the state, Essex lies near Glacier National Park, 31 mi southwest of East Glacier and 26 mi southeast of West Glacier.  Amtrak's Empire Builder makes a flag stop at Essex, westbound at 7:41pm and eastbound at 8:55am.  The Izaak Walton Inn hotel is by the Amtrak station platform.  Essex also is home to a BNSF Railway yard, where helper units used to push freight trains over Marias Pass are based. Fall River Pass (elevation 11,796 ft ) is a mountain pass in the Rocky Mountains of northern Colorado in the United States.  It is located in the Front Range, within Rocky Mountain National Park.  The pass is traversed by U.S. Highway 34 on Trail Ridge Road between Granby and Estes Park.  However, as at Milner Pass on the Continental Divide, the road does not descend after reaching the pass from the west, but instead continues to climb along a side ridge; thus, neither pass is the high point on Trail Ridge Road, which crests at 12,183 ft east of Fall River Pass, still within Rocky Mountain National Park.  On the other hand, the old, largely unpaved, and one-way-uphill Fall River Road (see adjoining map) does have its summit at Fall River Pass, where it joins the modern highway for the descent to the west. The Canadian Rockies (French: "Rocheuses canadiennes" ) comprise the Canadian segment of the North American Rocky Mountains.  They are the eastern part of the Canadian Cordillera, which is a system of multiple ranges of mountains which runs from the Canadian Prairies to the Pacific Coast.  The Canadian Rockies mountain system comprises the southeastern part of this system, lying between the Interior Plains of Alberta and Northeastern British Columbia on the east to the Rocky Mountain Trench of BC on the west.  The southern end borders Idaho and Montana of the USA.  In geographic terms the boundary is at the Canada/US border, but in geological terms it might be considered to be at Marias Pass in northern Montana.  The northern end is at the Liard River in northern British Columbia.
