PARKS – America's national parks aren't meeting the needs of this year's flood of tourists from the East.

The influx of Asian tourists in Jackson Hole has resulted in some cultural problems involving pit toilets around Yellowstone and Grand Teton national parks, the Jackson Hole News & Guide reports.

About a dozen of the 42 vault toilets in the park had broken seats this summer, Grand Teton park spokesman Andrew White says.

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.

Reports to The Spokesman-Review from Yellowstone Park visitors this season include tales of bus loads of Chinese -- apparently trying to set records for selfies with wild creatures -- were notably out of sync with park rules related to wildlife viewing.

Grand Teton plans to put up signs that will illustrate proper use of a lidded, elevated toilet.
