When conditions are perfect, the Gaylor Lakes area of Yosemite National Park can be a wonderful location for photographing star trails and the Milky Way. There are some drawbacks, however, not the least of which is a hike of about one mile starting at about 10,000 feet and going up about 600 feet before descending 250 feet to the shore of Middle Gaylor Lake. The second aspect that might give one pause is that the hike back is in near-total darkness.
Undeterred, our group started out about two hours before sunset and before long we reached a saddle ridge overlooking Middle Gaylor Lake—a classic alpine lake nestled in a broad basin—a sparkling blue oval below us. The scenery in all directions was spectacular, a sufficient reward by itself for the effort we had expended.
But we were here for the stars that would appear in a few hours and so we started scouting possible locations. As we did so, two hawks circled overhead and an occasional marmot gave us disapproving stares. But no other human was here, another payoff for the hike we had just completed.
My goal was to make a second attempt for the so-called ecliptic, the location in the sky where the field of stars appearing to rotate counter-clockwise around the north star borders the stars appearing to rotate clockwise around the southern hemisphere. I had come close at Mono Lake, but tonight I hoped for a more obvious display of the divergent lines.
If there had been no wind, the lake would have served as a mirror for the scene in the sky, but this was not in the cards for last night. But complaints were muted because near-perfection is not a bad deal when you think about it.
Thanks to Michael, our workshop leader, I was lined up nicely as the image below demonstrates. This image is in fact a composite of 20 exposures, each 4 minutes long taken in quick succession.

After about two hours of photographing star trails, the group gathered at the northern end of the lake to take advantage of the Milky Way’s location, hovering over the “infinity pool” edge of the shoreline. Our hopes for an end to the windy conditions continued to be disappointed, so there would be no mirror effects tonight. The image below is one of several taken, with the golden light of Fresno outlining the horizon to the south.
