From the peaks of the Stahlgaard Mountains, a frozen river of ice spills from a high cliff into a small, vaguely rectangular-shaped lake nestled in the valley below. Formed of runoff from the Stahl Glacier, its waters have a somewhat milky, iridescent blue-green to turquoise color due to fine-grained particles of copper, quartz, and feldspar carried into the lake by meltwater from the glacier that overlooks the valley, and remain quite frigid all year long. In fact, the water is so cold that it can kill a swimmer in as little as fifteen minutes. Nonetheless, the lake is rich in a variety of surprisingly large fish that survive year round in its cold waters, predominantly cutthroat, brook, bull, knucklehead, lake, and rainbow trout, as well as mountain whitefish and the occasional black bass, catfish, or ling, in addition to the odd coldwater crab or octopus, some of whom grow to be quite large. Gemstones and other minerals can sometimes be found in its waters, polished by the digestive tracts of its aquatic inhabitants.
Also known as the Lake of Red Tears, so named for the blood red algae which frequently blooms in its waters (see Flora), Diarfell Lake is approximately two and a quarter miles long and about two-thirds of a mile wide, with a maximum depth of about two hundred and thirty feet, and is drained on its southern shore through the Samark River.
Nestled along the edge of the Stahlgaard Mountains and its glacial lake, these small, scattered patches of thick woodlands are amazingly resilient, growing back whatever is cut in only a few short years. Known for the aggressive dire bears that live in the forested hills along the lakeshore, these woods (and their environs) have a fell reputation.
