Mushroom Rock Trail Closed to Horses, Hikers Use Caution
Mushroom Rock Trail is closed to horses due to hazardous conditions caused by recent flooding. Hikers use caution. Trail is washed out in place and may be difficult to follow.
The monument maintains an Air Quality Station which tracks visibility, particulates, ozone, nitrates, sulfides, dioxins, and rainwater deposition. This data is analyzed and used to determine overall air quality, and factors or events that may be having detrimental effects on the air. This information can help managers decide what future actions may be necessary to maintain the current level of air quality, or to make improvements. The monument's close proximity to Mexico makes it a prime candidate for monitoring the effect of Mexico's pollution on air quality in the United States. Smelting, manufacturing and power plants on the other side of the border produce pollutants that can be carried into the monument. That, along with plans to build an additional incinerator and power plants within 50 miles of the monument, makes it even more critical that baseline air quality data be collected.
Air quality data from 48 Class 1 NPS sites and others can be viewed on the Internet. See the links below.
Did You Know?
Chiricahua National Monument is home to many coati-mundi. Because the Chiricahua mountain range is situated at a biological cross-roads, species from Mexico's Sierra Madres make their way north. They are trapped here in our ‘sky-islands,’ though, by ‘seas’ of desert which they cannot cross.
