I don’t think I ever actually posted this, back in last April. This is a photo I took, from the summit of Mauna Kea. You can see the Sub-Millimete Array. down there. Those dishes are a bit spooky – they all move together, in total silence.
Also, you can see a bit of the local scenery. The thing that struck me about the summit was just how Mars-like it looks. Aside from the blue sky and the clouds, it really does have a Mars-like feel to it.
