Mastodon Trail winds through spruce forest for onehalf mile before entering a former forest fire burn area, then descends to the Nugget Creek Public-use Cabin at mile 12. The cabin is also accessed using the South Fork Winter Trail when the river is frozen solid. Be cautious. The Chena and South Fork rivers often have thin ice and open water, even in late winter.
