From personal experience, walking on snow/ice sounds different based on temperature. From my time of walking to work at 6am in Michigan when I was younger, I could tell the temperature in approximately 10 degree F increments based on the sound. At least between 30F to -10F
This is a well-known phenomenon in Nordic countries I believe. There is a verb "narskua" in Finnish which is only used to describe the sound of walking on snow in below freezing temperatures.
Google AI tells me:
"The Finnish word narskua translates to "crunch" or "scrunch" in English. It's an onomatopoetic verb that describes the sound snow makes when you step on it in very cold temperatures"
There's definitely many, many different sounds of snow and ice based on temperature, and probably humidity, pressure, etc. Or what those conditions were 2 days ago when the snow fell, what they were yesterday, and what they are now. I live in Canada, Québec so maybe that makes me some kind of subjective authority.
