Star Trail on Merced

Star Trail on Merced

Merced River outside Housekeeping camp, Yosemite National Park.

For the first time ever, I ended up staying at the housekeeping camp in Yosemite National Park. I have previously stayed at the tent city in Curry village – this was a treat. The housekeeping cabin consisted of three concrete walls, concrete roof, one canvas entrance, beds, and a patio with a fire ring. It was also right next to the Merced river. It was so cold in the night that the two space
heaters we got were life savers.

At night, I went and setup my camera and tripod with an intervelometer menaing to let it run through the night while I sleep happily. However, within about an hour, there was mist and then fog – I bailed out on this plan at this point. This photograph is a stack of the images in about a 50 min span.
