Arizona's wildfire season seemed to get an early start this year, and major blazes have already made major news. If you're planning a day trip or weekend excursion into or through Arizona's national forests, here are some tips for steering clear of fires.

Before you head out on a trip, we recommend you check the newly redesigned InciWeb, a website run by several federal agencies — including the U.S. Forest Service, the Bureau of Land Management and the National Park Service. The site features an interactive map where you can click on any currently burning forest fire, in Arizona or elsewhere, and get more information about it.

Each fire has its own page that includes an overview of the situation, updates about road or campsite closures, how the fire is thought to have started, what percentage of the blaze is contained, and information about any evacuations that have been ordered. For some fires, you'll also see an interactive map of the fire perimeter.

 

Each incident also has links you can use to follow the situation on Facebook, Twitter or other social media sites.

We hope you find this information helpful as you plan your vacation. And remember what Smokey Bear says: Only you can prevent forest fires — so be sure to adhere to the Leave No Trace principles of fire safety.

Video Captures Bobcat, Rattlesnake Facing Off in Phoenix Area

A real estate agent in Scottsdale recently came upon a startling sight: a bobcat doing battle with a rattlesnake on a nearby sidewalk.

As Valley news station ABC15 reported, Laura Lucky was out showing houses when she spotted the animals. In the video she shot, the bobcat paws at the snake as it tries to slither away. The snake strikes at the bobcat, but it's unclear whether it lands any bites.

Ultimately, the bobcat clamps down on the snake near its head and carries it out of view, into the desert.

Wildlife experts told the news station that bobcats are not immune to rattlesnake venom, but that it isn't unusual for the opportunistic felines to go after animals. As we recently reported, rattlesnakes are a more common sight in the Sonoran Desert this time of year, with temperatures on the rise.

It's Rattlesnake Season in Arizona: Here's How to Be Prepared

Spring means higher temperatures, and that means more rattlesnakes are out and about in the deserts of Central and Southern Arizona.

As Doug Kreutz of the Arizona Daily Star reported last week, Arizona is home to 13 rattlesnake species. Most of those can be found in Southeastern Arizona, and they typically begin leaving their dens around this time of year. As of last week, though, only one rattlesnake bite had been reported to Tucson's Arizona Poison and Drug Information Center, the Daily Star reported.

The center received about 160 reports of bites last year, but there were no fatalities reported in Arizona. On average, the center's director told Kreutz, fewer than five people in the United States die from rattlesnake bites every year.

That doesn't mean rattlers should be taken lightly, though. Here are a few tips, some of them from our Arizona Highways Hiking Guide, for avoiding a painful and potentially life-threatening bite:

  • The best place to find rattlesnakes is in thick ground vegetation — under, around and in large logs, and tucked into rock cracks. If you don't put your hands and feet in places you can't see, you probably won't be bitten. And don't count on the snake to use its rattle to warn you of its presence — baby rattlesnakes, typically born in summer, can't yet produce an audible rattle. Use a stick to bat the brush ahead of you before your feet get there.
  • At night, snakes like to sprawl on warm, flat ground and on asphalt, so use a light.
  • If you encounter a rattlesnake, take one or two steps back to get out of striking range. As a Coolidge man learned last year, you should not play with the snake.
  • If you are bitten, try to stay calm and sit still. If possible, get to a hospital quickly. If you must hike out on your own, set a moderate pace and remind yourself that this injury is not fatal.

Arizona Elk Rounded Up for West Virginia Reintroduction

Angela Ramsey Tucker | Woods Canyon Lake

We told you last summer about a plan to send some of Arizona's elk population to West Virginia for a repopulation project there. Late last month, that project finally got underway, with 60 elk being captured and quarantined in preparation for the journey.

The elk — roughly 50 cows and 10 bulls — were captured via helicopter at the Raymond Wildlife Area east of Flagstaff, the Arizona Game and Fish Department said in a news release. After pursuing each animal in a helicopter, Game and Fish workers fired a handheld "net gun" to entangle the elk, then blindfolded and sedated it before moving it to a quarantine pen.

The elk will head to West Virginia late this month, the department said. There, they'll join a handful of elk transplanted from Kentucky in 2016.

The project is a partnership between Game and Fish and the West Virginia Division of Natural Resources. It's only the second time elk have been transplanted from Arizona — the first was in 2000, when the state sent 26 elk to Kentucky. That population has thrived, and today, Kentucky has between 10,000 and 15,000 elk.

Of course, Arizona's elk are themselves the product of a reintroduction effort. Their ancestors were brought here from Yellowstone National Park starting in 1913. From those few handfuls of transplants, Arizona's elk population has grown to about 45,000, Game and Fish says.

An elk subspecies native to Arizona, the Merriam's elk, was hunted to extinction by the early 1900s.

Exotic Fish With Teeth Like Human's Found in Tucson Lake

An Arizona fisherman got a toothy surprise recently when he caught a fish native to South America in Tucson's Silverbell Lake.

As The Arizona Republic and other media outlets reported, Jeff Evans was fishing on the north side of the lake January 12 when he caught a pacu — a fish species known for its teeth, which are uncannily similar to those of a human.

If that seems like the stuff of nightmares ... well, we can understand, especially since pacus are related to piranhas. But pacus mostly eat plants, experts say — even though Evans told The Republic that this pacu tried to bite him a few times.

How did this pacu end up in Silverbell Lake? It likely was dumped there by someone who bought it as a pet, then released it when it grew too large, according to a spokesman for the Arizona Game and Fish Department. Doing so with an invasive species can crowd out the native and stocked fish in a waterway, the department said.

The species is on Game and Fish's list of species that cannot be purchased in Arizona without a permit, but illicit purchases still occur, officials said. One Game and Fish worker said he's seen 10 to 12 pacus caught in the state over his 26-year career.

The department advised anyone in a similar predicament with a pet pacu to find another way to deal with it — such as by returning the pacu to the pet store.

Fountain Hills Receives Rare Honor for Dark-Sky Preservation

The town of Fountain Hills, on the edge of the Phoenix area, is best known for its namesake 560-foot water feature. Now, it's getting worldwide recognition for something even higher in the sky.

The International Dark-Sky Association (IDA) has named Fountain Hills an International Dark Sky Community. It's the 17th city or town worldwide to receive that honor; it's also only the second such community to be located near a major metropolitan area. The IDA works to preserve areas of darkness so that stars, galaxies and other celestial wonders remain visible at night.

Scott Feierabend, the IDA's executive director, called the designation "an important moment for the movement to preserve dark skies in the American West."

A group of Fountain Hills citizens, who later formed the Fountain Hills Dark Sky Association, began pursuing the designation three years ago, partly out of concern that the advent of bright LED lights would contribute to light pollution. As a result of the group's efforts, the town's outdoor lighting and sign ordinances were updated to address new causes of light pollution.

Mayor Linda Kavanagh said the town has pursued dark-sky-friendly policies since its incorporation in 1989. Many residents attend local star parties or even maintain domed observatories in their backyards.

Arizona's other International Dark Sky Communities are Flagstaff, Sedona, the Village of Oak Creek and the Kaibab Paiute Tribe's land. The IDA also designates International Dark Sky Parks, and that list includes several sites in Arizona. In addition to Grand Canyon National Park, Grand Canyon-Parashant, Wupatki, Sunset Crater and Walnut Canyon national monuments are on the list, as are Oracle and Kartchner Caverns state parks.

Park Service Seeks Public Input on Non-Native Aquatic Species Plan

Non-native fish continue to threaten native species in the Grand Canyon area, and the National Park Service is looking for public comment on a plan to manage the situation.

The Park Service hopes to expand its management plan for non-native aquatic species in Grand Canyon National Park, along with the section of Glen Canyon National Recreation Area that's below Glen Canyon Dam. Its expanded management plan and environmental assessment are open for public input through January 5.

An expanded plan is needed, the Park Service says, because of an increase in green sunfish and brown trout, two non-native species, in these areas. Additionally, the agency says, other non-native aquatic species have become an increasing threat to native species since other management plans were completed in 2013 and 2016.

The plan is in the scoping period, meaning this is an opportunity for the public to weigh in early in the planning process. The Park Service will host a webinar November 28 — plus open houses December 6 at Glen Canyon National Recreation Area, December 7 in Flagstaff and December 12 in Phoenix — to provide more information on the proposal and solicit feedback.

For more information on the proposal and the public meetings, or to comment electronically, visit this link.

Grasshoppers Threaten Southeastern Arizona Crops

An unusually high number of grasshoppers are causing damage to crops at properties in the southern part of Arizona, according to a recent report.

The Arizona Daily Star reported that the grasshoppers, which arrived at farms in Southeastern Arizona in September, have been munching on cantaloupes, corn, greens and other crops. The U.S. Department of Agriculture said the population surge seems to be isolated to that area of the state.

A University of Arizona professor told the newspaper that the increase likely is a result of three consecutive years of well-spaced rainfall during the summer monsoon. That allowed plants to flourish and provided more food and habitat for the grasshoppers, he said.

Grasshoppers, as their name suggests, usually prefer to eat grass, but they'll eat whatever is available if all the grass is gone. Arizona has the greatest diversity of grasshopper species in North America, the UA professor told the Daily Star.

There's good news for farmers, though, the newspaper reported: More grasshoppers likely means more birds that prey on them. And that could mean fewer grasshoppers in the area at this time next year.

Wildfire Could Mean Extinction for Mount Graham Red Squirrels

Mount Graham red squirrel | George Andrejko, Arizona Game and Fish Department

An endangered squirrel species found only in the Pinaleño Mountains of Southeastern Arizona was heavily impacted by a forest fire this summer, federal wildlife officials say.

According to a new survey, Mount Graham red squirrels, found only on their namesake peak and other mountains in the Pinaleños, now number only 35 in the wild, the Arizona Daily Star reported last week. That's a dramatic decrease from the more than 250 of the squirrels estimated in last year's survey, the U.S. Fish and Wildlife Service said.

The decrease is due to the Frye Fire, a lightning-caused blaze that burned 48,000 acres in the Pinaleños this summer, a Fish and Wildlife Service official said. Steve Spangle, Arizona field supervisor for the agency, added that he's "not optimistic" about the species' survival.

“We’re very worried about a critter going extinct under our watch,” Spangle told the Daily Star. “It doesn’t mean we won’t do what we can."

The annual squirrel census found evidence of fire activity in 95 percent of surveyed areas, and 80 percent of those areas showed at least some habitat loss.

Mount Graham red squirrels, one of more than 20 known subspecies of red squirrels in North America, were listed as endangered in 1987. Besides the Pinaleños, the only other known living specimens are five squirrels in captivity at the Phoenix Zoo, the Daily Star reported.

Spider Rock: How Canyon de Chelly's Iconic Spire Was Formed

In our October issue, we featured Canyon de Chelly National Monument on the Navajo Nation. That canyon's best-known feature is Spider Rock, a sandstone spire that rises more than 700 feet from the floor of the canyon. It's named for Spider Woman, a key figure in Navajo lore. And it was what prompted Bob Klages, a reader from Oxford, Michigan, to write to us. (It actually was the second time this year that Bob has asked a great question; the first was about Petrified Forest National Park's logs.)

"How does nature carve away all the rock around a spire like Spider Rock, leaving 700 feet of such a skinny needle formation like that?" he asked. We didn't have an answer, and as it turned out, neither did the monument's staff. So we contacted Harold "Hal" Pranger, chief of the Geologic Systems Branch of the National Park Service's Geologic Resources Division.

Spider Rock, Pranger says, is the last remnant of stream and hillslope erosion process that continue to make the canyons deeper and wider. He writes in an email: "Spider Rock at one time (many thousands to perhaps even hundreds of thousands of years) was connected to the ridge between the main Canyon de Chelly and Monument Canyon. The hillslope and stream erosion processes worked at different rates along that ridge, obviously at a slower rate right at Spider Rock. The differential erosion left this tower that is now called Spider Rock behind."

Eventually, Pranger adds, Spider Rock will topple, as have other rock monoliths in the national monument. For now, though — and likely for centuries to come — it's a highlight of any visit to Canyon de Chelly.

If you'd like more information about the monument's geology, you can check out a report the Park Service produced in 2007.
