This should be of interest to all those planning a Whitney trip: CalTopo Blog: Sentinal Satellite Imagery
Read the blog post for more details, but in short, CalTopo is now offering high-res satellite imagery updated every week
. This is a real game-changer for trip planning, particularly in this big snow year to see what areas are melting out each week.
For now this is being offered for free, but I'll give the unsolicited plug that a CalTopo subscription is a great value and very handy.
