Oldest human footprints will soon be on public view

History buffs love to see the places where famous people walked, but how about the thrill of seeing where some of mankind’s earliest ancestors strolled by? Footprints dating back 3.6 million years were discovered at Laetoli in Tanzania by the famous paleontologist Dr. Mary Leakey back in 1976. The prints of three individuals and several animals had been pressed into a layer of ash deposited by a nearby volcano and became fossilized as more and more ash and dirt piled up and pressed the lower layers into a soft rock called tuff.

This find is of major importance to the study of human evolution but the site itself hasn’t been open to the public for 15 years. Now Tanzanian officials have announced that the footprints will again be on view. The prints are in the Ngorongoro Conservation Area, which already attracts about 400,000 tourists annually.

The tracks are those of three individuals walking upright. One walked in the footprints of another and all lead in the same direction. It’s unclear what hominid (early form of human) made the tracks, but several skeletons of the Australopithecus afarensis were discovered in the region and date to the same approximate period. The famous Lucy skeleton is an Australopithecus afarensis. The photo shows a reconstruction of one at the Cosmocaixa museum in Barcelona.

Scientists are currently studying how to open the site with minimal impact. They expect the process to take up to two years.

This is the latest round in a continuing controversy over how to preserve the prints. Some scientists say the entire section of rock should be removed and placed in a museum. Others say they’re much more compelling where they were found. A protective sealant was placed over the prints in 1995 and the whole area was covered with earth. While this has kept the prints in good condition, it means nobody gets to appreciate them. Hopefully Tanzanian scientists will find a way to preserve the prints while allowing visitors to enjoy this one-of-a-kind discovery.

Oprah Winfrey introduces Yosemite National Park to her audience

When it comes to influential television personalities it is difficult to top Oprah Winfrey. After all, the queen of daytime television has been making authors rich for years with her book club and its no secret that her endorsement of a product, sends her audience out to the shopping malls. Now, the National Park Service is hoping they’ll be the recipients of a little Oprah magic thanks to two high profile episodes about her recent camping trip to Yosemite National Park.

Oprah, along with her best friend, the ever-present Gayle King, spent a week in Yosemite awhile back, “roughing it” in a pop-up RV and exploring the stunning landscapes that the park is so well known for. They also found some time to do a little fly fishing, go hiking, and even cooked their meals over an open fire. The first episode of Oprah’s camping adventure aired last Friday and the second is due to be broadcast today. (Check local listings to see when it airs in your area.)

The excursion came about after Ranger Shelton Johnson, who has spent 18 years working for the Park Service, wrote to Oprah asking her to consider visiting Yosemite. Johnson, who is African-American, told the talk show host that not enough black people visited the parks, and that perhaps she could help change that with a visit of her own. With African-Americans making up less than 2% of the visitors, Oprah has her work cut out for her, but these two episodes may bring Yosemite some much needed exposure. It is likely that for many viewers, these shows are giving them their first ever glimpse the place.

Encompassing more than 1200 square miles of California wilderness, Yosemite is best known for it’s legendary rock formations, Half Dome and El Capitan, both of which are popular draws for rock climbers. The park also offers beautiful alpine meadows, giant sequoia trees, and deep mountain valleys, allowing visitors to hike more than 750 miles of trail or bike the 12 stunning miles of the Yosemite Valley. For adventure travelers it is quite the outdoor playground and visitors who just come to take in the view will find plenty to love as well.

As for Oprah, it’s unlikely that she’ll be back soon. While it seems that she and Gayle had a reasonably good time on their outdoor adventure, she did tell her audience “I’d never do that again” in reference to their camp out. I guess we can’t expect her to be hiking the Appalachian Trail after she retires from television next year, huh?

Denali National Park seeks artist in residence

Are you an aspiring artist looking for some inspiration? Do you enjoy the great outdoors and have a desire to paint spectacular landscapes? Then Denali National Park has an opportunity for you. The park is now taking applications for its artist in residence program, seeking qualified artists to visit during the summer of 2011.

Each of the residency programs is ten days in length and comes with the use of the Murie Cabin, located at Mile 43 along the Park Road. The cabin was the base of operations for Adolph Murie, who conducted a ground breaking study on the predator-prey relationship between wolves and sheep back in the early 1940’s. The cabin sits at a very scenic site in Denali, offering access to some of the best landscapes in all of North America, although the accommodations are a bit spartan. The cabin comes equipped with a propane heater, necessary even during the Alaskan summer, a stove, refrigerator, a small library, and double beds. There is no electricity or running water however, and an outhouse out back provides bathroom facilities.

The ten day residencies take place between June and September of next year and the artists selected will be responsible for their own food and travel. Additionally, the position offers no monetary compensation, and the artist is expected to create at least one piece of art and donate it to the park. They are also expected to make one public presentation of the piece they create. In exchange for their work, they’ll receive free use of the cabin and access to some of the most spectacular backcountry on the planet, which should serve as fantastic inspiration for their art.

Park service dedicates ‘trail of time’ at Grand Canyon

The National Park Service is hosting a ribbon cutting ceremony along the South Rim of the Grand Canyon today as they dedicate a new trail that has been hundreds of millions of years in the making. The official ceremony will take place at 2:30 PM local time, with an informal hike along the trail taking place between 3:00 and 5:00 PM. The event is part of the park’s celebration of Earth Science Week.

The new path has been dubbed the “Trail of Time” and it is designed to be an interpretive walk that focuses on the amazing geologic processes that are on display in and around the Grand Canyon. The new exhibit follows an existing trail, but incorporates some interesting new elements that help to define the magnitude of the natural forces that are on display to visitors. For instance, there are now brass markers every meter along the route, with each of those markers representing 1 million years of geologic history. Viewing tubes have also been added which help to put into context where certain visible rocks fall along the Earth’s historical timeline.

The Trail of Time can be hiked in two different directions. If visitors start at the Yavapai Geology Museum they can walk backwards in time, slowly approaching the oldest rock in the park, the Elves Canyon gneiss. This ancient formation is more than 1.8 billion years old. On the other hand, hikers who begin at the Verkamp’s Visitor Center will actually move forward in time, approaching the youngest rock in the Grand Canyon the Kaibab Limestone, which is a mere 270 million years old.

The Grand Canyon is one of the best places on Earth to view first hand the impressive geological processes that go on around us on a daily basis. Those processes are so small that their effects can only be seen over the course of millions of years, but in the Canyon, more than a billion years of Earth history is open to examination, giving a all a very humbling glimpse into the powerful forces that are in play on our planet.

National Parks app comes to the iPhone

Visitors to America’s national parks now have a new high tech option for learning more about those amazing places. Last week the National Parks Conservation Association released an app for the iPhone, iPad, and iPod Touch that offers up a wealth of information on 50 of the most popular parks in the country, including Yellowstone, the Grand Canyon, and Yosemite. (For a complete list of the parks covered click here.)

The app is completely free and provides information on the plants and animals that travelers can expect to find in the various parks, including the ones that are poisonous and dangerous, something this always helpful when you’re not sure if your about to step into poison ivy or not. You’ll also find comprehensive lists of threatened and endangered species, as well as a brief history of each of the parks, including great photos from each location as well.

But that’s not all. The app also allows you to find parks that are close to your current location and offers directions on how to get there. It includes information on making reservations at each park, directions on how to find the visitors center, and current news from the park system on featured parks as well.

The field guide app was developed in conjunction with eNature.com, a company with an extensive database of information focused on wildlife. That database has been created by top biologists, zoologists, and conservationists, and contains information on over 6000 different species. That information is now, quite literally, delivered to the fingertips of visitors to the national parks.

There is one caveat to using the app however, as a data network is required to download the information. The iPhone will work where cell service is available, although in more remote areas of the parks that can be spotty at best. iPod Touch and iPad users will need to use wifi, which is available in some visitor centers, to load up their maps and information ahead of time. Keep that in mind when relying on this app to help guide you through the parks.
