Having been to Nepal a few times, both this century and last, and an active member of whiteblaze, I was surprised to see no thread about the horrible earthquake and devastation going on there.
As I know many experienced hikers from the US and whiteblaze have been to Nepal, I am sure there are thoughts and prayers of the many friends and Sherpas and good, humble Nepali people we have met there.
I have 4 friends who were there 2 days ago during the earthquake and have just now heard from the last one, and they are all OK and 2 have now gotten out, one is at the airport and one lives there permanently and is helping out in downtown Kathmandu.
I know it's hard to find reliable, aid organizations that don't siphon huge amounts of $ off the top, but here is a list of 7 vetted charities that should be trustworthy that are helping there now, in case you want to help:
Here is a picture of downtown Kathmandu from one of my trips 10 years ago

From pics I'm seeing online, I'm sure it doesn't look like that now.
