The document outlines the geological events that have occurred in the Edmonton River Valley, focusing on a detailed cross-section of the area near the University of Alberta. It lists a sequence of formations and deposits, including the Belly River, Bearpaw, and Horshoe Canyon formations, as well as various geological processes such as erosion and landsliding. The exercise encourages understanding of the complex geology by subdividing the Cretaceous bedrock and analyzing the timeline of events.

1. We will now try to repeat this exercise for the Edmonton River Valley. Notice that the below cross-
section (as seen during the River Valley Tour lab) is much more complex than the simple cross
section in Question 5. Using all the evidence you have garnered thus far (including previous
questions, your constructed cross-section, and the detailed cross section below) complete the
account of the geological events that have occurred in the Edmonton River Valley near the
University of Alberta. Hint: For the Cretaceous bedrock you'll want to subdivide it into the 3 units
we discussed when completing your geological cross section below Edmonton earlier in this
lab.Oldest (First event to occur) 1. 2. Belly River Formation deposited Bearpaw Formation
deposited 3. Horshoe Canyon Formation deposited Empress Formation deposited! 4. Till
deposited Glacial Lake Edmonton deposits deposited Sand dunes deposited Mazama Ash
deposited 11000 year old river terraces deposited 6. 8000 year old river terraces deposited
Erosion (unconformity) 7. Landsliding 8. 9. 10. 11. 12. Youngest (Last event to occur)
