I am a Groundskeeper at Boyce Thompson Arboretum. These photos were taken early on New Years Day inside the Succulent Display House at Boyce Thompson Arboretum. The heater had not come on as it should and these beautiful patterns were created on the glass panes during the night. After the heat was turned on Nature's art quickly melted and disappeared. The icicle photos were taken on the High Trail. Unfortunately very large sections of the trail were covered with ice so we had to close the trail to the public. I took the icicle photos as we were checking the High Trail in the early morning.
