There was both good and bad news from Glen Canyon National Recreation Area, where 14 adult quagga mussels have been found attached to moored vessels and dock structures in Lake Powell. The word that the invasive pests have turned up in the big lake isn't good, but all is not yet lost in the battle to keep the invades out of the lake. None of the mussels were close enough together for successful reproduction.

More than a decade after it was closed in the wake of the September 1, 2001, terrorist attacks, the Port of Boquillas border crossing at Big Bend National Park is back in business.

It's National Park Week, so hopefully you're finding some time to get out into the parks. If you do, you can reflect your visit with a photo album from Shutterfly.

Audio tours at Paterson Great Falls National Historical Park, potential political tinkering with the Antiquities Act, and reviving the organ at Scotty's Castle in Death Valley are among the items in this week's roundup from around the parks.
