Crepuscular rays

Crepuscular rays shine down on the Wasatch. According to Wikipediacrepusculum is latin for twilight, and you usually see this optical phenomenon near sunrise or sunset. There is an optical illusion here. Though the sun's rays look like they converge at a point the rays are actually parallel, much like the train tracks shown below. The rails look like they converge at some distant point, but they are really parallel (otherwise a train would have a difficult time going anywhere).
