Jon and the group of Classic climbers made it to Everest base camp. He called from his sat phone and said that it's going well but it is exceptionally cold. They'll be there a couple of days and then head back to Lobuche. The wifi at base camp is not up and running yet so he does not have access to email to send pictures to the blog.
IMG posted some pictures of base camp. If you click the top picture on the April 9th post, you can see Jon at the back of the dining tent on the left. Click "Next" and it scrolls through a lot of good pictures of base camp and the mountain.
Here's the link to track his location:
