Features
shown on the topographic map of Mt. Abbott, California:
- Arete
- Indicated on the map by closely spaced contour lines revealing a
steep sided ridge. The arete separates two U-shaped valleys.
- Glacier
- Shown on the map by a white background (ice) and blue contour
lines. One glacier is labeled in red, but six other glaciers or partial
glaciers also appear on this map. These are all examples of cirque
glaciers.
- Horn
- Shown by closely spaced, closed contour lines, indicating a steep
mountain peak.
- Moraine
deposits - The unconsolidated material typical of moraines is
indicated by brown dots/speckles on the map. The could be either an
end moraine or ground moraine.
- Paternoster
lakes - The chain of lakes within the glacial valley is indicated
by blue on the map, as are the connecting rivers.
- U-shaped
valley or glacial trough - A relatively flat, wide bottomed valley
is indicated by widely spaced contour lines on the map. The valley
walls are shown by contour lines located closer together indicating
the steep sides of the valley walls.
