Trying to cover 394 units of the National Park System is no easy task. Here at the Traveler we couldn't even make a dent into that task without the welcome and generous support of a long cast of contributors.

After all, this web-zine is an all-volunteer operation with a small staff of fervent park advocates. The more than two dozen other individuals listed here -- some who regularly grace the pages, some only occasionally -- contributed material posted in the Traveler during 2010. Their contributions provided a wealth of information and helped craft a portrait of the diverse park system.

While much of the content is supplied by myself and Contributing Editors Jim Burnett and Bob Janiskee, there are a number of regular writers.

David and Kay Scott are well-known for their guidebooks to national park lodgings, and they've gone above and beyond our expectations in terms of keeping readers abreast not only of those lodgings, but also of their travels through the National Park System. Remember their summer-long odyssey on the Oregon and Lewis and Clark trails?

Danny Bernstein began filing regular dispatches for the Traveler in 2010, reporting on such diverse topics as maintaining sections of the Appalachian National Scenic Trail and park interpretation to hiking in Great Smoky Mountains National Park. She's also been busy cranking out a diverse number of checklists on a range of parks.

Aaron Deschane has been our out-of-sight but highly valued podcast producer. Without his talents (and patience) we couldn't have provided you with a range of interviews running from Ken Burns and long-distance blind hiker Trevor Thomas to National Park Service personnel talking on topics as varied as sea turtles to where Confederate Gen. Thomas "Stonewall" Jackson's arm is buried.

And, of course, thanks to Chris Miller, the tech who keeps the Traveler running smoothly.

Here are the rest of the writers who broadened our reach in 2010, and some of the photographers who helped bring the parks alive with their images. To them, and anyone we might have inadvertently omitted, we extend our heartfelt thanks and appreciation:
