Frosty morning steps

There's a light mid-morning dusting of frost casting the green grass cyan. Adventurer, your eyes lead you upwards through a steep leafed tunnel into the unknown gloom.
Wait here in the chilling discomfort with the hope of a sunbeam at least some hours away, or risk misadventure on the stairs?
I'm a drone, so, I'll now fly back to the invigoration of my charger, but you must decide with your legs.
