Thanks Frans
I didn't get a measurement on this, but it was in the 3mm range. That's good to know about the term snow flea, I'll be more careful what I call these now.

Isotoma viridis
Given it is a few mm. I. viridis is one of the 'snow fleas' = Collembola that are active on the snow surface. Note that 'snow flea' is a very inaccurate name for IDing springtails as it groups members of unrelated families. There are also Collembola that are active below 0 degrees: the 'ice flea' or 'glacier flea'. Other inaccurate names that group several different springtail species...
Note that I. viridis is quite variable in background colour and in pigmentation.
