On Saturday we spent the day slowly working our way up the volcanic mountain stopping to take photos the entire way up. I could see the storm cloud building above the mountain throughout the day and had a secret hope that by late afternoon conditions would be right for a rainbow at the top. I didn’t say anything though because I didn’t want get everyone’s hopes up. Luckily though as we came over the rim and descended into the caldera this was the sight that we encountered. Our timing was fortuitous indeed, the rainbow lasted less than ten minutes and then silently vanished.
