Question

Problem Set #6-worth 6pts The topographic map below is from a USGS 7.5' quadrangle map of Mt. Logan Pass, MT. Sketch two simple qualitative (not to scale), small topographic profiles for the section lines X-Y and W-Z. Which of these valleys is more likely to have formed from glacial erosion? Why? Profile X-Y Profile W-Z Label two examples of horns (H), two examples of aretes (A), a cirque that contains a tarn (C-T), and a small hanging valley with a waterfall (HV) 16600 Siyeh UV 5400 Mtn Slyeh Pass Mtn 98 Bend To THE CIER ION ARK 096

Explanation / Answer

Profile WZ is most vulnerable for form valley due to glacial erosion because of the gradient is much more than the profile X Y. Horn observed on map. (1) left of siyeh bend just above profile WZ (2). Near top right of given toposheet (at Craker about 9200 m amsl). Aret ( 1) Around bottom left corner which is m marked by red curve line. ( 2). Top of the toposheet (Preston park). Cirque (1) Right corner of the toposheet 2. Left of siyeh pass 2. Near matahpi. Hanging valley 1. Near cataract mountain (top left corner of the toposheet)
