Into The Interior
From Rainy Pass, the route continues up the mountain, past the tree line to the divide of the Alaska Range, and then passes down into the Alaska Interior. The elevation of the pass is 3,200 feet (975 m), and some nearby peaks exceed 5,000 feet (1,500 m). The valley up the mountains is exposed to blizzards. In 1974, there were several cases of frostbite when the temperature dropped to −50 °F (−45 °C), and the 50-mile-per-hour (80-kilometer-per-hour) winds caused the wind chill to drop to −130 °F (−90 °C). The wind also erases the trail and markers, making the path hard to follow. In 1976, retired colonel Norman Vaughan, who drove a dog team in Richard E. Byrd's 1928 expedition to the South Pole and competed in the only Olympic sled dog race, became lost for five days after leaving Rainy Pass, and nearly died.
The trail down Dalzell Gorge from the divide is regarded as the worst stretch of the trail. Steep and twisting, it drops 1,000 feet (300 m) in elevation in just five miles (8 km), and there is little traction so the teams are hard to control. Mushers have to ride the brake most of the way down, and use a snow hook for traction. In 1988, rookie Peryll Kyzer fell through an ice bridge into a creek, and spent the night wet. The route then follows Tatina River, which is also hazardous: in 1986 Butcher's lead dogs fell through the ice, but landed on a second layer of ice instead of falling into the river. In 1997, Ramey Smyth lost the end of his pinkie when it hit an overhanging branch while negotiating the gorge.
Rohn is the next checkpoint, and is located in a spruce forest with no wind and a poor airstrip. The isolation, and its location immediately after the rigors of Rainy Pass, and before the 75-mile haul to the next checkpoint, makes it a popular place for mushers to take their mandatory 24-hour stop. From Rohn, the trail follows the south fork of the Kuskokwim River, where freezing water running over a layer of ice (overflow) is a hazard. In 1975, Vaughan was hospitalized for frostbite after running through an overflow. In 1973, Terry Miller and his team were almost drawn into a hole in the river by the powerful current in an overflow, but were rescued by Tom Mercer who came back to save them.
About 45 miles (70 km) from Rohn, the path leaves the river and passes into the Farewell Burn. In 1976, a wildfire turned 360,000 acres (1,500 km) of spruce into blackened badland of burnt timber. Fallen trees, and falling through clumps of sedge or grass which balloon out into a canopy two feet (600 mm) above the ground, supporting a deceptively thin crust of snow, are common dangers. The Burn forces teams to move very slowly, and can cause paw injuries.
Nikolai, an Athapaskan settlement on the banks of the Kuskokwim River, is the first Native American village used as a checkpoint, and the arrival of the sled teams is one of the largest social events of the year. The route then follows the south fork of the Kuskokwim to the former mining town of McGrath. According to the 2000 census, it has a population of 401, making it the largest checkpoint in the Interior. McGrath is also notable for being the first site in Alaska to receive mail by aircraft (in 1924), heralding the end of the sled dog era. It still has a good airfield, so journalists are common.
The next checkpoint is the ghost town of Takotna, which was a commercial hub during the gold rush. Ophir, named for the reputed source of King Solomon's gold by religious prospectors, is the next checkpoint. By this stage in the race, the front-runners are several days ahead of those in the back of the pack.
