The Teklanika River is a 91-mile (146 km) tributary of the Nenana River in the U.S. state of Alaska. The Nenana is a tributary of the Tanana River, which is part of the Yukon River drainage in the central interior region of the state. Flowing northward from headwaters at the Cantwell Glacier in the Alaska Range, the Teklanika drains an area widely visited by tourists to Denali National Park and Preserve. The park's only road crosses the river at milepost 31 and a National Park campground is located on its eastern bank at milepost 29.
On its course, the river travels north from the core Alaska Range as a braided river, becoming rapid and narrow as it traverses through the Primrose Ridge, braiding again through the Stampede Trail valley, narrowing again through the Tekla Ridge before ultimately meandering through a complex series of oxbow turns and lakes across the southern Tanana River valley.
In the book Into the Wild, the Teklanika River is referred to as the Rubicon for American adventurer Christopher McCandless. Since then, the river has proven an often deadly obstacle to many hikers attempting to reach the bus where McCandless camped-out and later died of starvation.
In August 2010, a Swiss hiker, Claire Ackermann, drowned in an attempt to cross the river while tied off to a rope that was strung by previous hikers between trees on both shores. While she drowned on state land, her body was pulled ashore by her French boyfriend a short distance downriver. That point was on Denali National Park land, triggering a dispute between Park Rangers and State Troopers as to jurisdiction.
In June 2020 the bus used by McCandless was removed because of public safety concerns. The 1940s bus was taken to the remote trail in 1960 and used as accommodations by a road crew, according to Denali Borough Mayor, Clay Walker. In 2019 a newlywed Belarusian woman drowned trying to cross the swollen river on her way to the site. A stranded Brazilian had to be rescued in April 2020 and five Italians were rescued in February 2020, with one suffering from severe frostbite. In total 15 bus-related search and rescue operations for visitors to the bus were carried out between 2007 and 2019. It was air-lifted by a US army Chinook helicopter.
On September 24, 2020, the Museum of The North at the University of Alaska (Fairbanks) announced it became the permanent home of McCandless' 'Magic Bus 142' where it will be restored and an outdoor exhibit will be created.
