Named for John Thomas Dillon (1947-1987), former geologist with the Alaska Division of Geological and Geophysical Surveys who spent ten years mapping the geology of the southern Brooks Range. He crashed in his plane while returning to Fairbanks from the range at the end of the 1987 season. Named in a decision by the Board on Geographic Names in 1990.
Dillon Mountain lies 1.5 miles due east of the Dietrich River bridge at milepost 207 on the Dalton Highway. The mountain was named in 1990 and therefore the name does not appear on the 1975 topo map. A good starting point to climb the mountain is from the parking area on the west side of the highway just across the Dietrich River bridge. You want to be on the north side of the river here so you don't have to cross it on the route to the mountain. Head SE from the highway across a swampy low plain for about 1 1/4 miles to a low saddle just north of the small hill with elevation 2003 ft. shown on the map. As you approach the saddle there is an old road that you should find which will help hiking. The saddle is at UTM 385400E, 7504100N. Follow the road until it starts descending then leave the road and head east toward the south end of the ridge of Dillion Mountain. Turn north up the ridge as soon as you pass the steep eroded cliffs. As you reach the top, stay to the right (east) side of the crest and continue north. The ridge is not simple as it has about four uplifted bands of rock running from west to east across the main ridge. These are easiest to cross lower down on the east side. After the last rock band start climbing up steep, loose scree and sand to the east ridge coming down from the summit. The upper parts of this ridge are better climbing and it leads right to the top. The route is 3.5 miles with a gain of 3400 ft. and takes about 5 hours. The return hike takes about 3 to 3 1/2 hours. 8/95 RLC
Recent data: From Lists of John the prominence value for this peak is 2270 ft.
