Wait a minute…. Explain “daily satellite imagery.” So if I am camped for 2 nights, by night 2 I see my truck?
It is daily imagery updates but the resolution is no where near good enough to see something that small. I find it very useful in the spring for determining snow coverage. It is definitely not like having your own access to a spy satellite. There are also weekly images available in a better resolution but you are always running the risk of cloud coverage.

CalTopo provides realtime data from NASA's MODIS and GEOS and ESA/Copernius' Sentinel.

NASA MODIS over past few days. Clear days show snow coverage (note slight change between 17th and 23rd in valleys) and a cloudy day on the 21st. All the satellite layers are shown at 50% so it's not an accurate representation of overcast on the cloudy day.

But to give you some idea of resolution I put a view at 62,500 scale over the Forest Service topo around Georgetown and Loveland. You can get a sense of snow coverage but you're not going to be able to tell the exact day when a trail clears. Each daily satellite pixel on that image is about 750' x 750'.

I’m so old school

THIS! It's called going on an adventure. Pure and simple. Take all the old maps you can find too. Never throw a paper map away. Be aware of Gazetteer's "Updates", however. Older versions show more trails, in my experience, than the newer ones do.

This is true of many maps, paper and digital (such as PDF MVUMs) both. I try to keep old Trails Illustrated, BLM and USFS maps that show trails that have been closed. Just in case, ya know.

Precisely. (Imagine your own meme).
