Panorama 1 of 4. On the horizon at the left is a bit of Twin Peaks and Sutro Tower. Continuing to the right, there is a forested area, which is probably Mount Sutro, and then a residential bump which would be Mt. Olympus. Next is a barren hill, which would be Corona Heights, and finally, the forested Buena Vista Hill, with St. Joseph's Hospital outlined in front of it. The street at the left is 20th Street, and at the very bottom, marked with trees, is Interstate 101. Above that is a residential section of Potrero Hill, east of Potrero Avenue. The thin brick tower in the upper middle is the fire training tower at Shotwell Street and 19th Street. In the exact center of the slide is a long, double gabled, gray building on 19th Street between Harrison Street and Alabama Street.
