Despite the lack of photos of the tunnel, Cats Canyon provided many opportunities for photographers to capture the Mountain Route throughout the rail line's existence. The following photographs are just some of the scenery along the route:
|Cats Canyon, looking south, circa 1880s. The old Santa Cruz Highway is at right, with the train tracks possibly|
heading into a tunnel at bottom-center. The Alma-Los Gatos Flume rides the hillside at left.
|Narrow gauge engine #13 heading around the bend toward Tunnel #1 just south of Los Gatos, 1882.|
|Stereoscopic image of a narrow-gauged train in Cat's Canyon, c. 1890s.|
|Narrow-gauged railroad steaming toward Los Gatos from Alma, with the Los Gatos (Box) Flume on the hillside at left.|
|A narrow gauge train crossing over a wooden trestle heading north toward Los Gatos, circa 1895.|
|A train heading through the gap that was once Tunnel #1. Cats Canyon is a very dangerous and unsteady gorge,|
so avalanche rails were installed in especially dangerous areas, visible at top-right. Photo from 1905.
|Tracks just south of Cats Canyon, possibly after a heavy rain considering the amount of debris and siltation, 1906.|
|A beautiful perspective shot of Cats Canyon around 1910. Glenwood Highway is at right while the tracks are at left.|
The site of the former tunnel is right where the tracks round the bend. The flume is still visible at left, above the tracks.
|The straight, even tracks running left toward Lexington, while above Glenwood Highway meanders around the curves.|
|The right-of-way at the entrance to Cats Canyon beside Los Gatos Creek. Highway 17 is visible at right.|
The right-of-way has been largely turned into a bicycle route until it reaches Lexington Reservoir.
