The Subway, Zion National Park

Zion Subway

“Slot” canyons — of which the Subway is one — are the darlings of southwestern US geography. They are narrow defiles carved in layers of sandstone hundreds of feet deep — so narrow that it is difficult to walk through them in places, and so deep that sunlight may reach to the bottom only a few minutes a day when the sun is directly overhead. They are often in remote wilderness locations, and require heroic hiking, climbing and/or swimming skills to navigate. Slot canyons attain their unusually tall and narrow forms due to flash floods that carry tons of fine sand that can grind though the soft sandstone relatively quickly.

One of the finest of these is “The Subway” in Zion National Park, so named because the flume at the bottom has an oval shape reminiscent of a train tunnel. True to its kind, it is very hard to get to, a long distance from trailheads on very rough, sometimes dangerous trails. The photographer is awarded an extra penalty, not only having to pack in heavy gear, but to do part of it in the dark so that the light on scene is just right. Attacking The Subway in the fall is a great choice, not only because the midsummer heat is absent, but because colorful fall leaves adorn the stream and canyon bottom. (Pricing Schedule B)
