It's the rime of the season

Photographer Mark Cline found himself in a frosty wonderland last weekend in Jay Cooke State Park. He captured these crystals on the swinging bridge there, which required a steady tripod when no one was actually moving on the bridge.

All month there have been delightful morning scenes across the county as foggy and clear nights have left frosty blankets on everything outside. Rime ice is formed when water droplets in fog freeze to solid surfaces like trees. Hoar frost often forms on clear nights, when water vapor in the air skips the liquid stage and freezes directly onto surfaces. The end products of either phenomenon are barely distinguishable.

Cline also shared several other photos, which are also posted here.
