Nice to see progress reaching the valley. The High Mountain Office (OHM) in Chamonix has put many of the Mont blanc refuges into Google earth

it is pretty cool as you can see the nearby refuges directly then consult their details by clicking on the waypoint.
Remember that the Google photographs are taken during the summer so conditions will vary at other times of the year.
