greatest elevation change in Edmonton

[Dave D.]

I am curious to know where the greatest elevation change lies in Edmonton, not the highest and lowest points in different areas, but an actual drop from an embankment into a ravine or valley. I think there must be somewhere where the drop is greater than from the McDonald Hotel down the stairs to the river. For example, I recall from years ago a steep drop into a ravine in the Saddleback Road area of south Edmonton. Any thoughts on where the greatest drop lies and how many feet down it is? Many thanks.

There's quite a few cliffs along the river valley, especially the further west you get that literally go from river valley top to river... check the north bank just west of the Quesnel bridge

Yep, the cliffs of Patricia Heights are pretty much vertical into the river.

Southwest of the Quennel it basically ranges from "straight down" to "nearly straight down."

I was hoping someone would have done some surveying and could say the biggest drop is 150 feet or 200 feet, or that someone could direct me to an online elevation map for Edmonton. This isn't scientific at all, but the banks on the south side of the river appear to be higher than some of the 20-storey towers that stand above them, so maybe 200 feet?

If you have access to GIS software, you should be able to find a free DEM covering the area, though the resolution won't be very good. Alternatively, check out Toporama with access to NTS maps, though once again, the detail wouldn't be great.

Check the Digital Elevation data at http://geobase.ca/geobase/en/data/cded/index.html

It may be of use

The average west of downtown is ~175 feet with some spots near the Quensel just north of 200'. The banks are a bit shallower east ranging from 50' to 100'.
