This low-level, large-scale colour infrared photo shows natural vegetation in the central part of
Three small lakes 5 that are almost black because they reflect little infrared exist in this area. The northernmost is ringed by low-lying aquatic vegetation 6 with some algae growth 7 offshore. Trees that are imaged as greenish-yellow have been killed by water in several locations 8.
