Wildlife Adapt to their Environment

The primary purpose of the Grasslands is the management of 419,495 acres or range lands and another is Wildlife Management of approximately 275 different species of birds that use or live here. Quail, pheasant, dove, bald eagle, golden eagle, badgers, ducks, geese and hawks, lesser prairie chickens and longbill curlew are just a few. There are just about forty different species of reptiles, nine amphibians, eleven fish, and lion, bear, antelope, fox, and bobcat are among the mammals. Given the sparcity of trees these creatures adapt to their habitat amazingly well. They sometimes dig in for cover under the sandy soil to avoid falling prey to predators.

Dinosaur Tracks

The dinosaur tracks are located in the Purgatoire Valley, called Rio de las Animas Perdidas en Purgatorio or River of Lost Souls. The site of the trackway is named Picket Wire Canyonlands and extends 1/4 of a mile. It is North Americas largest tracksite containing over 1,300 footprints in four different layers of rock. The illustration provided by the US FS Comanche National Grassland, shows the type of footprints found in the shoreline strata. The Picket Wire Canyonlands site could be considered the national treasure of dinosaur footprints!

dinosaur tracks
The tracks are 150 million years old and were made by two types of dinosaurs, Allosaurus and Brontosaurs. Forty percent of the tracks were left by Brontosaurs, plant eating dinosaurs, accompanied by younger Brontosaurs heading west along the shoreline. The smaller tracks weave around the larger in a playfull fashion. The other sixty percent of the tracks were left by the Allosaurus. They were two footed, three toed and ferocious meat eating scavengers hunting in packs.

 

Rock Art

Rock Art images some of which may be 375-4500 years old have been found in Picket Wire Canyonlands. They were left behind by nomadic people who were hunters and gatherers who the followed migrating game making their visits to the area short. Photos courtesy of USFS Comanche National Grassland.

Intriguing as they may be, these lands offer an incredible amount of history and dates from 150 million years old dinosaur tracks to late 1800 homesteads. These sites hold important clues to our past and we need your help to preserve and protect these valuable resources. If disturbed, important clues to our past will diminish forever. Removing, damaging, or even moving evidence destroys a site's scientific, and often aesthetic value for future visitors. Rock art is particularly sensitive. Please photograph but do not touch or apply any photographic enhancing or replication materials. These sites on public lands are protected under federal law. Please report any acts of vandalism, defacement, or theft to the U.S. Forest Service Office in La Junta, (719) 384-2181 or Springfield (719) 523-6591

Please do not touch or disturb rock art in any way!

Most Native People's language was not written, only spoken. When two tribes with different dialects met, they often communicated with hand signs, and this practice is still sometimes used today. Martineau's ability to recognize graphic representations of these hand movements allowed him to inspire historians and archaeologists all over the West. We also recommend his book, The Rocks Begin To Speak (Library of Congress Number 72-85137).


The Dolores Mission and Cemetery was built between 1871 and 1889 by Mexican Pioneers. Ruins of the Mission and Cemetery are still visible, pictured at right. Photos courtesy of USFS Comanche National Grassland.

The Rourke Ranch also known as the Wineglass Ranch, was a cattle and horse ranch, founded by Eugene Rourke in 1871. Three generations of the Rourke family lived and worked on the ranch ensuring its survival over a span of a hundred years. When the ranch was sold in 1971, it was known as one of the oldest and most successful enterprises in southeast Colorado expanding from Eugine's original settlement of 40 acres to well over 52,000 acres. New Byway placed interpretive signs have been installed.

Picket Wire Canyonlands became part of the Comanche National Grassland, December 3, 1991. 16,000 + acres of land was transferred from the U.S. Army through congressional legislation to the U.S. Forrest Service (Public Law 101-150). The U.S. Forest Service is mandated by law to protect and conserve the natural resources in Picket Wire Canyonlands. Interim guidelines have been developed to protect and conserve precious, non-renewable resources in the canyon and still provide appropriate public access. We encourage you to stop by or call the Comanche National Grassland Office in La Junta, Colorado for current weather and road information on Picket Wire Canyonlands. They are located at 1420 E. 3rd Street, just east of Vanhooks Fruit Market off of Highway 50 in east La Junta, (719) 384-2181. Office hours are from 8:00 am to 12:00 pm and 1:00 pm to 5:00 pm, Monday through Friday.

SAFETY TIPS

GOOD PHYSICAL CONDITION is essential to the enjoyment of your hike as well as to your personal safety. Know your limits and the limits of the weakest member of your group. You are only allowed in the canyonlands area from dawn to dusk, so plan your hike carefully. Overnight camping is not allowed in Picket Wire Canyonlands.
SOLO HIKING CAN BE EXTREMELY RISKY and requires careful attention to planning and to potential safety hazards. Always notify someone of your expected route, departure and return times. In case of emergency, call the Otero County Sheriff Office, (719) 384-5941 or 911.
THERE IS NO DRINKABLE WATER in Picket Wire Canyonlands. Carry at least 1 gallon of water per person. Thirst will not occur until you are already dehydrated, so drink before you are thirsty.
BE PREPARED FOR THE HEAT, temperatures in the summer range from 90 F to 105 F. You will be walking in direct sunlight for the entire trip. Prepare for sudden weather changes. Afternoon thunderstorms are common.
SUNSCREEN, SUNGLASSES, A HAT AND INSECT REPELLENT are highly recommended.
WEAR PROPER ATTIRE! During summer, cloths should be loose fitting and provide enough cover to protect your body from the sun. Wear a hat. During spring and fall wear several layers of clothes so you can adjust to temperature changes. A rain parka is also suggested as sudden storms can occur in the afternoon. We recommend high-top hiking boots that are well broken in before your hike or you could be disabled with painful blisters. Carry moleskin or molefoam and use it as soon as you feel a "hot spot," do not wait until the blister has formed. "Tennis" shoes are not recommended because they offer little protection from prickly pear and cholla cactus that are abundant throughout the canyon. Socks are also important. Two pairs can help lessen friction and heat as long as they do not unduly constrict your feet within the boot.
FLASH FLOODS CAN OCCUR WITHOUT WARNING at any time of the year. If you find yourself in a flood situation, climb to the highest possible point immediately.
A FIRST AID KIT is strongly recommended.
AVOID TALL GRASS! Watch where you place your hands and feet. Prairie rattlesnakes, scorpions, tarantulas, and badgers are common. Generally, these animals are as afraid of you as you are of them.
PETS SHOULD BE RESTRAINED, Do not let them harass wildlife.
Carry out all trash, including cigarette butts.
