It froze this morning and windchill was still at freezing when we made it out to the lake. The sky was absolutely beautiful with streaks of contrail like an air show. [Edit: Swapped the last photo with another] 📍 George H. Sparks Reservoir

What “contrail” means
Wiktionary · Wikipediacontrail
- nounAn artificial cloud made by the exhaust of jet aircraft or wingtip vortices that precipitate a stream of tiny ice crystals in moist, frigid upper air.
Contrails or vapour trails are line-shaped clouds produced by aircraft engine exhaust or changes in air pressure, typically at aircraft cruising altitudes several kilometres/miles above the Earth's surface. They are composed primarily of water, in the form of ice crystals. The combination of water vapor in aircraft engine exhaust and the low ambient temperatures at high altitudes cause the trails' formation.
