A few weeks ago I visited Professor Angel Boy and DIL in SF. While DIL was at work, my son and I walked to Glen Canyon Park (or Glen Park Canyon) from their home.

Who knew this deep pocket of wilderness is steps away from high density living in the middle of the city?

Everything is either UP or DOWN. It was quite a strenuous workout, especially since I had to keep up with my six-foot-plus son.

We were looking for the coyotes that live in the canyon. My son saw one recently on a previous visit and we hoped to see him or her again, but we had no luck.

Lots of raspberries. Twin Peaks.Angel Boy is always lightyears ahead of me.

The free flowing Islais Creek. It was a little hazy in the afternoon. I hadn’t traveled with my good Canon — pics were taken with Canon point and shoot.  Finally, he turned around. You can tell he’s saying, “Hurry up, Mom, and stop taking so many pictures!”According to Wiki: The park and hollow offer an experience of San Francisco’s diverse terrains as they appeared before the intense development of the region in the late 19th and the 20th centuries. The park incorporates free-flowing Islais Creek and the associated riparian habitat, an extensive grassland with adjoining trees that supports breeding pairs of red-tailed hawks and great horned owls, striking rock outcrops, and arid patches covered by “coastal scrub” plant communities. In all, about 63 acres (25 ha) of the park and hollow are designated as undeveloped Natural Area. Elevations in Glen Canyon Park range from approximately 225 feet (69 m) above sea level at the south end of the park to 575 feet (175 m) above sea level at the north end and along the east rim of the canyon; the walls of the canyon are extremely steep, with many slopes approaching a length-to-height ratio of 1:1
