### Instruction:
What are the places McCaw travelled to capture movements of the Sun?
List them in a comma separated format.

### Input:
McCaw was born in Daly City, California, in 1971. He has a BFA from the Academy of Art College in San Francisco.

McCaw is known for his large-format homemade cameras in which he uses expired gelatin silver photo paper and long exposures to make solarized paper negatives which often include the burned path of the sun within the frame, in a series named Sunburn. McCaw travels to remote places to capture different apparent movements of the sun, including the Arctic Circle in Alaska, the Galápagos Islands and the Mojave Desert. McCaw's earlier work used a 7×17 inch view camera to create large-format negatives from which he made platinum prints. Projects following Sunburn include work with a modified Cirkut camera, resulting in exposures that can take more than 24 hours. A series titled Poli-optic employs a homemade camera with a grid of lenses. Finally, the series Heliograph includes work in which there are multiple exposures of the sun on the same paper negative.

### Response:
Arctic Circle in Alaska, the Galápagos Islands, the Mojave Desert.
