If the landscape appears more flat, make sure that the Terrain box is selected under Layers. To see a ground level photo open the Court of the Patriarchs disclosure triangle and click on the link. The Navajo Sandstone overlies the red mudstones of the Kayenta formation that are much more easily eroded. Using the Springdale East topographic map, what is the elevation (immediately below the yellow pin) of the boundary between the cliff-forming Navajo and the slope-forming Kayenta? (Dont forget to alternate the opacity to determine the boundary.) Provide your answer in feet (to the nearest 100 ft). NOTE: we are asking for the elevation at which the topography changes from shallow slopes to much steeper slopes. The steeper slopes correspond to the Navajo Sandstone, which has a color change midway up.

Air rising from the surface at the ITCZ piles up to form relatively high pressure in the upper troposphere where air diverges to the north and south. Once this air has had its moisture removed as rainfall and cools down, it sinks as the other side of the Hadley Cell from the ITCZ. Required:At about what latitude does it sink back to the surface to form a high pressure/divergent zone and what sort of biome do you often find at this latitude?
