I used this link:
https://www.freemaptools.com/elevation-finder.htm

to find the following:

Mount Ida = 1511.0 meters
Salmon Arm valley floor near my Mom's house = 353.0 meters
Salmon Arm top of Tank Hill on Hwy 1 = 476.00 meters
Where I live, out of town, while technically in Salmon Arm = 529.00 meters

So, if the snow level drops by 193 meters every week, that means 5 weeks to snow.

Booooooooo.
