No Meteors, So Some Pictures of a Sunset Instead
The mountains around the Dardanelles don't look like your typical Sierra Nevada peaks: they look more like flat-topped mesas in the picture above. They are not composed of granite, but instead are the remnants of lava flows and volcanic mudflow deposits that erupted from a volcanic center that was similar to today's Cascades. The difference? These eruptions were happening 9-10 million years ago, and the volcanic center died away. Erosion took over and stripped away most of the volcanic rocks except for these remnants.
We were getting a little concerned about the cloud cover. Huge thunderheads had been building over the eastern Sierra, and some clouds were starting to spill over the mountains towards the west. Lousy for looking at meteors, but maybe nice for sunset. Or a lightning show...
