Releasing a flood of controversy on the Colorado River

Since the completion of the Glen Canyon Dam in 1963, the once warm and muddy Colorado River has run clear and cold, with a drastically altered ecosystem. A new plan to release regular, intentional floods — to resupply sediment and restore species habitat — aims to reverse the damage done to the Grand Canyon’s natural systems over the last 50 years.

Geologic Column: The double-edged sword of commercialization

Everyone has a mental image of a “commercialized” geologic site — Niagara Falls, anyone? My vision includes crowds, noise, clutter, distracting visual stimuli, neon signs, traffic, and a price on everything from scenic views to water. Souvenirs, including T-shirts, snow globes, shot glasses and fudge, are usually for sale.

Geologic Column: Snow globes, light shows and t-shirts

It seemed like a simple question. “What do you think the most commercialized geologic site is?”

My curiosity had been piqued by a trip through Wisconsin Dells, a glacially carved river valley that has the world’s largest concentration of water parks (complete with the requisite fudge shops, tchotchke shops and miniature golf courses). Before that trip, my top nominee would have been Natural Bridge in Virginia, which has featured the seasonal sound-and-light show, “Drama of Creation,” since 1927. Today, the site can be rented for a conference or a wedding.
