Stephen Ingram (Member 7,328) was driving to his track club workout in Long Valley, Eastern Sierra Nevada, California, US when he looked to the east, across the White Mountains. ‘I almost drove off the road,’ he said, ‘when I saw these dramatic crepuscular rays.’

Crepuscular rays are beams of light and shade that can appear to radiate from the Sun as the shadows from clouds are rendered visible by atmospheric haze. In Stephen’s case, the haze was the result of smoke from distant forest fires, while the shadows were cast by Stratocumulus clouds. In parts, these were also producing showers that dissipated away in the drier air below to appear as cloud tendrils known as virga. ‘It goes without saying,’ said Stephen, ‘I was late to the track that day.’
