OpenStreetMap
One of the tricks I’ve learned with ID editor is to try different satellite sources:
USGS Topographic Maps - may give you name of natural features.
USGS Large Scale Imagery - is low quality, but may show winter pictures, for example allowing to trace trail in a deciduous forest.
DigitalGlobe Standard Imagery - is low quality, but seems to be most up to date (20015?)
Esri World Imagery - new layer, high quality, just showed up a few days ago. Some places it is same as Bing, for some places it seemed newer.
As always, be mindful of only using sources that allow being used for OSM editing.

And in particular in areas where all of these as well as Bing and Mapbox only offer either clouds, snow or images from the stone age (in the US in particular Alaska - look for example in the Talkeetna Mountains or the Neacola Mountains) there is a whole lot of open data imagery available some of which you can also find in ID and other editors.
