Alluvial Fan, Rocky Mountain National Park
The Alluvial Fan is a fan-shaped area of disturbance in Rocky Mountain National Park. It was created on July 15, 1982, when the earthen Lawn Lake Dam above the area gave way, flooding the Park and nearby town of Estes Park with more than 200 million gallons of water. Enormous boulders were displaced, and trees and earth were ripped from the ground.

Black newly applied sealcoat contrasts with unsealed asphalt
Newly applied coal-tar-based sealcoat is dark black, sharply contrasting with the unsealed asphalt parking lot below. Coal-tar-based sealcoat is a potent source of polycyclic aromatic hydrocarbons (PAHs).

Black sealcoat contrasts with unsealcoated asphalt on parking lot
Sealcoat, marketed to protect and beautify the underlying asphalt, sharply contrasts here with the light gray of unsealcoated asphalt pavement. Read more about coal-tar-based sealcoat and PAHs here.

Sealcoat wear indicated by bare asphalt patches
The abrasive action of car tires and snow plows causes sealcoat to wear off. Here, light-colored patches indicate where the sealcoat has worn off and the underlying asphalt shows through.

Worn sealcoat around a storm drain.
Coal-tar-based sealcoat, a potent source of polycyclic aromatic hydrocarbons (PAHs), abrades into fine particles with time. Here, runoff containing abraded particles goes down a storm drain and is delivered to a nearby lake. Read more about coal-tar-based sealcoat and PAHs here.
