Canyonlands National Park - Happy Canyon - Maze District

The Maze district of Canyonlands is one of the most remote sections of National Park in Utah, requiring 4-wheel-drive vehicles and permits for any overnight use. Happy Canyon runs from Glen Canyon National Recreation Area into the Maze district from the west, and the gradual slope means visitors can hike along it to enter or exit the lower sections of the park.

Description The blackbrush forms a nearly continuous canopy on the higher ground above Happy Canyon in The Maze. Juniper has expanded its range from the small drainages; young individuals are now occupying the higher, drier ground within the stands of blackbrush. Juniper encroachment into grasslands and shrublands has been common across the West the past half-century. This phenomenon has been attributed to livestock grazing and fire exclusion.

Description This late autumn photo shows blackbrush interspersed with healthy pinyon and juniper. Pinyon and juniper in the foreground ehibit branch and whole-plant dieback due to the early 2000s drought. Young juniper that have established within the blackbrush patches show few effects from the drought, however.
