What is tokositna glacier?

As an AI language model, I don't have personal experience or emotions, but here are the relevant information about the Tokositna Glacier:

• The Tokositna Glacier is located in the Talkeetna Mountains of Alaska, USA, in the Denali National Park and Preserve.
• It covers an area of approximately 70 square kilometers (27 square miles) and has a length of around 38 kilometers (24 miles).
• The glacier is a valley glacier that is fed by a massive icefield, which receives an average of 5 meters (16 feet) of snowfall every year.
• The Tokositna Glacier has been receding in recent years, losing an average of 30 meters (98 feet) in thickness per year since the 1950s according to a 2016 study by the National Park Service.

Visitors to the area can book flightseeing tours or helicopter rides that offer views of the glacier and surrounding mountains. However, caution is advised for hiking or ice climbing in the area, as glacier travel carries inherent risks.
