A closer look at cliff and stones in fluorescence, also lichens. The blue stones are probably fluorite, the orange cliff is feldspar and golden lichens. Lichens fluoresce in "gold" (yellow/orange) due to natural pigments like xanthones and atranorin, especially under UV light, revealing hidden colors not seen in daylight. Feldspars crystallize from magma, this area was vulcanic 1,9 billion years ago.

In the sky bright planet Jupiter and a lot of airglow, even some faint aurora borealis.
