JACKSON, Wyo. (AP) — The influx of Asian tourists in Jackson Hole has resulted in some cultural problems involving pit toilets around Yellowstone and Grand Teton national parks.

Grand Teton park spokesman Andrew White tells the Jackson Hole News & Guide that about a dozen of the 42 vault toilets in the park had broken seats this summer. Park officials discovered that tourists from Asian countries were squatting, with their feet on the lids, while using the facilities.

The weight was causing toilets to snap where the hinges connect the lid to the bowl. White says Asians typically squat on toilets in their home countries. Visitation from Asia is anticipated to keep climbing. Grand Teton plans to put up signs that will illustrate proper use of a lidded, elevated toilet.
