With the conclusion of a successful peregrine falcon nesting season, the National Park Service has reopened several popular rock-climbing routes in Zion National Park.

Four juvenile falcons were fledged from one nest; another nest inhabited by a breeding pair produced no offspring.

Thirteen routes were closed last March.  Only a few haven’t been reopened.

Peregrines were near extinction in the 1970s but are now flourishing.  They were removed from the Endangered Species List in 1999.
