Figure 3. Map showing the distribution of post-impoundment sediment in Lake Mead. Areas of thin post-impoundment sediment cover (< 1 m, shown as pale purple) are mostly along the floors of the tributary valleys, while thick sediment cover (> 1 m, shown as dark purple) is mostly along the floor of the original Colorado River valley.
