Fall is creeping down toward Montreal, Canada, from the surrounding higher elevations, the reddish-brown of fading forests replacing summer’s green. This image of the region was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite on October 6, 2005. Although the land in the valley between the Ottawa River and the St. Lawrence Seaway still displays quite a bit of green, some golden areas have appeared as well. To the south, autumn has turned the Adirondack (bottom center) and Green Mountains (bottom right) a brilliant reddish brown. To the north, the lake-dotted expanse of Quebec province has turned color as well.
