MODIS true color: snow cover, and autumn color

Signs of the Autumn season show up nicely on MODIS true color imagery (above): snow cover is gradually becoming established in parts of the northern and central Rocky Mountains, as well as the northern Black Hills of South Dakota (close-up MODIS images centered at Denver, Colorado and Rapid City, South Dakota) — the snow cover is confirmed by the dark red enhancement in the MODIS false color image (below), which uses the near-IR Band 7 to detect a strong ice signal. In addition, the amber hues of Fall tree color are beginning to increase across the UP of Michigan (photo) into north-central Wisconsin (close-up MODIS image of Wisconsin). The amber colors of the vegetation across much of northeastern Iowa and southeastern Minnesota are due to harvested corn and wheat fields that are now dormant.
