Hatcher Pass (3886 ft./1148 m.) is a mountain pass through the southwest part of the Talkeetna Mountains, Alaska. It is named after Robert Hatcher, a prospector and miner. The nearest incorporated communities are Palmer and Wasilla approximately 12 miles (19 km) to the south, and Willow approximately 26 miles (42 km) to the west. The communities are at an elevation of approximately 250 feet (76 m) in the Mat-Su valley.
From the west, the pass is reached from the Parks Highway by a road winding approximately 40 miles (64 km) up the valley of Willow Creek. The pass divides the alpine headwaters of Willow Creek on the west from Fishhook Creek and Independence Bowl on the east side. To the east the road drops into and follows the Little Susitna River canyon downstream, and south, some dozen miles to the abrupt mountain front at the edge of the broad Matanuska-Susitna Valley. The road is unpaved and minimally maintained for about 20 miles (32 km) over the pass. This central portion of the road is usually closed by snow from late September to July. Although closed to car traffic, this section of road is heavily traveled in winter and spring by snowmachines and skiers.
Mills, adits, sky-trams, and other extensive early-1900's mine workings throughout the area of the pass record the activity that brought the road in. Now only a handful of people live and work in Independence Bowl, and none in the surrounding valleys.
There are no known historical native settlements in the area, although Dena'ina Indians hunted for caribou, sheep, and moose in the western Talkeetna Mountains until the 1930s. Human development in the area, including the road over the pass, is almost entirely due to gold mining.
Almost all the land around the pass is public; there are numerous widely distributed small private land holdings, mainly mineral estates. The area is popular for daytrip recreation; sledding, skiing, snowmobiling, hiking, camping, hunting, white-water kayaking, berry-picking, climbing, recreational gold-mining, mountain biking, etc. Independence Mine State Historic Park consists of 271 acres (1.10 km2), with well-preserved mine buildings, and a mining museum which offers underground mine tours, in Independence Valley, an alpine valley just below the pass. A large tract of land organized as the Hatcher Pass State Management area includes and surrounds the State Park and the pass.
Food and lodging is available at The Hatcher Pass Lodge in Independence Valley.
The area has a rich skiing heritage. Historic photos show miners recreating on skis. In the 1930s, Anchorage skiers were bused to the Fishhook Inn to use the rope tow there. That was only one of several small rope-tow ski lifts that have operated near the pass over the years up to the 1960s, although only traces of them can be found now. Many proposals to build a modern alpine ski area have been advanced over the years. In 2005 the Mat-Su Borough extended the electric grid and built a short access road to the proposed site of a base lodge.
The pass is one of the most popular road-accessible backcountry skiing areas in the state. Usually it is the first urban-accessible area of Alaska to get skiable snow in the fall.
The backcountry alpine skiing season generally extends from late September to late April.
Groomed skate and diagonal skiing trails winding amongst historical mining facilities in the high alpine area near the Hatcher Pass Lodge and the museum have a season that typically extends from October to April.
The first 10 kilometers of a Nordic ski area in the forests and glades at Government Peak Recreation Area the base of Government Peak were opened in December 2012 and a chalet was built in 2013. Additional trails and trail lighting are scheduled to be installed in 2016.
Snowmachines are prohibited within large areas of the Hatcher Pass State Management Area that are frequented by skiers. There are several backcountry huts in the area; a wilderness loop can be traveled over the mountain passes and glaciers linking these huts.
Hatcher Pass is in the Willow Creek mining district. Over 500,000 ounces (14,000,000 g) of gold has been produced from the district. The first mining claims were staked in the Hatcher Pass area in 1906. Underground hard-rock mining of gold from quartz veins accounts for most of the mineral wealth extracted from the Hatcher Pass area, although the first mining efforts were placer mining of stream gravels, and placer mining in the area has continued sporadically to this day. The first mill in the area started operating in 1908. Underground mining continued at a variety of locations around the pass until 1951. In the 1980s, one of the area's hard-rock mines was briefly re-opened. At least one mining company is actively exploring for gold in the area now.
The Fishhook Road rises to 3,886 feet (1,184 m) to cross Hatcher Pass at the head of Fishhook and Willow Creeks in the southwestern corner of the Talkeetna Mountains. The area has been heavily glaciated. Steep-walled cirques, jagged aretes, and hanging valleys above U-shaped valleys characterize the terrain. Trees grow only in the lowest valley bottoms. Brush, often dense, grows on lower mountain slopes, yielding to open tundra as elevation increase. Glaciers occupy the headwaters of major drainages. Some nearby peaks are over 6,000 feet (1,800 m) tall.
The Willow Creek district at Hatcher Pass is historically the third-largest lode-gold producing district in Alaska, having produced 624,000 oz of gold. At Hatcher Pass proper the southwestern margin of the Cretaceous to Tertiary age Talkeetna Mountains batholith is in fault contact with a pelitic schist. The Talkeetna Mountains batholith in this area consists of a pervasively altered zoned 74 Ma (million years old) tonalite body underlying Hatcher Pass and the headwaters of Willow Creek, and a 67 Ma quartz monzonite pluton farther west. The schist to the south consists mainly of metamorphosed and deformed sedimentary rocks, of Late Cretaceous to Paleocene age. The schist may represent subducted Valdez Group that was exhumed in the forearc region from beneath the Peninsular terrane. Both deformed and undeformed small felsic dikes occur in the schist. Several bodies of serpentinite are contained within the schist. Unmetamorphosed Late Paleocene to middle Eocene terrestrial sedimentary rocks of the Arkose Ridge Formations lie to the south of the schist and intrusives, across a low-angle detachment fault. Those bedded rocks are derived from the schists and intrusive rocks to the north. A rock unit variously mapped as as intricately intermixed amphibolite and quartz diorite, or as a migmatite, occurs in contact with the Arkose Ridge formation on Government Peak and in contact with the Arkose Ridge Formation and quartz monzanite east of the Little Susitna River. It is not clear if the migmatite is a higher-metamorphic-grade equivalent of the schist.  
Gold-bearing (+/- Ag, W, Sb, As, Cu, Mo, Pb, Te, Zn, Hg) veins occur in the tonalite, in small amounts in the schist, and in the Jurassic? migmatite, but not in the western quartz monzonite or in the Tertiary sediments. Most of the mineral deposits are close to the tonalite-schist contact.
The Castle Mountain Fault is a major tectonic feature. It strikes ENE and passes a few miles south of Hatcher Pass. It can be clearly seen crossing the Hatcher Pass road where concrete barriers and fencing protect the road from landslides of the "incompetent" rocks on the fault trace. Studies show that magnitude 7 earthquakes can be expected to occur on this fault with approximately a 700-year recurrence interval. The last big earthquake was probably 650 years ago.
Activities that can be enjoyed in the Hatcher Pass area include Nordic skiing, downhill skiing, mountain climbing, white water kayaking, rock climbing, mountain biking, paragliding, hiking, snowboarding, and back country camping. Hatcher Pass Road is a good paved biking trail until Mile 17 when the road changes to gravel.
The Gold Mint Trail provides miles of technical, rocky, gently-climbing mountain bike riding alongside the Little Susitna River. A downhill 2-mile bike trail with 1000 vertical feet of drop was built in 2013 in between switchbacks of the Hatcher Pass road at 16-mile. Four miles, in two stacked loops, of singletrack bermed flow-style bike trails were opened at the Government Peak Recreational Area in 2014, with additional trails scheduled for construction in 2016.
