First Excessive Heat Warnings of the Season
The first heat wave is poised to hit the Inner Grand Canyon this Saturday, June 5th, 2010 and the National Weather Service (NWS) has issued a Hazardous Weather Outlook for the weekend. The NWS may also issue its first Excessive Heat Warning of 2010 in the next couple of days as temperatures for the Inner Grand Canyon could reach as high as 110 degrees by Monday. These "dog days" of summer will last from now until early September, although the Arizona Monsoon Season (June 15th - September 30th) and its pattern of thunderstorms can offer temporary afternoon relief.
Excessive heat is the number one weather related killer in the U.S. with more than 1,500 people dying each year from heat associated situations. After blisters, this is the most common malady in the canyon, bar none. Initial symptoms include headache, pale and sweaty skin, cramps, nausea and vomiting, and fatigue. The symptoms usually progress as water loss increases. If not treated, your skin will turn red and hot and you will soon become disoriented, irritable, combative and ultimately unconscious.
Remember that the human body is 60% water and a canyon hiker can lose 20% of that water in one day of hiking, (or about 12 to18 pounds, which is equal to about 1.5 to over 2 gallons of water). The chronological order of heat related injury for the average person goes something like this: After sweating about 2% of your body weight your thirst mechanism is triggered. At 3% your performance is reduced by about 10%. Around 3 to 4% loss and heat exhaustion and muscle cramps set in. Then, at about 5%, your body begins losing a severe amount of muscle strength and endurance and you begin to make really bad decisions. By the time your body has lost 6 to 9% of its water weight, incapacitation sets in and you are unable to stand. Next comes the onset of total delirium and coma, when you reach 20% you are gone. Anyone choosing to hike into the canyon during periods of high heat should make sure to heed the following safety rules...
1). Avoid Strenuous Activities
Do not hike inside the canyon during the hottest time of day, between 9:00 a.m. and 4:00 p.m. Find a cool shady place to rest until temps moderate. Consider hiking at night, especially when the moon will provide some illumination.
2). Stay Out of the Direct Sun
Exposure to full sunshine increases your own personal "heat index" by about 15 degrees. Plus the fact that getting a sunburn makes the cooling process much more difficult.
3). Dress Accordingly
Wear loose, lightweight and light colored clothing, preferably cotton since cotton stays wet longer and therefore keeps you a bit cooler for a longer period of time. I like to keep a wet cotton hanky or neckerchief around my neck to help cool too.
4). Eat Accordingly
Avoid heavy proteins that increase water loss and also increase metabolic body heat production. Consume more carbohydrates and simple sugars for energy.
5). Drink Lots of Water
Start drinking extra water a few days before your trip and drink sport drinks with electrolytes a couple of hours before you begin your hike and while on the trail. Sport drinks containing electrolytes help keep your body chemistry balanced when sweating a lot. Especially in the summer season you will need to drink nearly a quart of water and/or sport drink for every hour of hiking. Drink enough fluids that your urine runs clear and avoid alcohol or caffeine, and consult your physician if taking antihistamines or antidepressants. Don't take salt tablets unless directed by your doctor.
** If you find yourself or someone else in your group suffering from the heat be sure to have them rest in a cool, shady spot. Slowly drinking copious amounts of water and/or sport type drinks can help. If symptoms progress, aggressive cooling is required so spray the victim with cool water and fan them while massaging muscle cramps as needed. Evacuate immediately if incapacitated. **
Hike Safe & Have Fun!

North Rim of Grand Canyon Now Open
The quiet North Rim of Grand Canyon National Park was officially opened last Saturday, May 15th at 7:00 a.m., when the Arizona Department of Transportation unlocked the gate at Route 89A and Route 67, a forty mile drive which leads to the Park's North Entrance. All roads are now cleared of snow and ready for traffic, although there is still about 35% snow coverage on the ground. The North Rim receives about one-tenth the number of visitors than the South Rim, and while a visit to the South Rim is said to average six hours, time spent by visitors at the North Rim averages three days. North Rim services will remain open until mid-October of 2010. Just to let you know, there will be prescribed burns in the North Rim area during the next thirty days.
All South Rim Trails Now Clear of Snow, but...
All South Rim trails are reportedly clear of snow and ice, but trails on the North Rim (1,000 feet higher in elevation from the South Rim) including portions of the Arizona Trail, Nankoweap trailhead access, and many other trailhead access roads may still be covered with 1-2 feet of snow. Access to Point Sublime from the W-1 Road may not come about until mid-June, so plan accordingly.
Central (Cross-Canyon) Corridor Water Availability
Water along the central corridor trails (Bright Angel, South Kaibab & North Kaibab Trails) is now available at all cross canyon water spigots, except for Supai Tunnel on the North Kaibab. Water sources along wilderness trails are quickly drying so make sure you check with the Backcountry Information Center for updates to ephemeral water availability.
Central Corridor (Inner Canyon) Campgrounds Full in May
Bright Angel, Indian Garden, and Cottonwood Campgrounds along the cross-corridor are reporting 100% full during May and 95% full during the month of June. Permits for late June, July, and August are readily obtainable - because most people do not enter the canyon during these times of extreme heat (average of over 100 degrees in the shade) plus the Arizona Monsoon Season (officially from June 15th - September 30th) brings violent thunderstorms with the accompanying danger from lightning and flash floods.
Temperatures Flirt with the 100 Degree Mark
It has been a nice, reasonably comfortable spring season at the Grand Canyon. Inner Canyon temperatures, on average, reach 100 degrees in early May. So far we've held it off but the Nat'l Weather Service projects that temperatures at Phantom Ranch will reach close to 100 degrees by this Friday, May 21st followed by another brief cool down. Remember to be off the trail between the hours of 8:00 a.m. and 4:00 p.m. during times of extreme heat.
A Safe Year, so far...
No deaths , (save for a couple of apparent suicides), have been reported yet this year. 2009 had many people succumb to various tragedies including suicides, drownings, heart attacks, hantavirus, and heat related deaths. An average of twelve people die at Grand Canyon National Park annually and during last year it seemed that every few weeks a new misfortune and befallen a canyon visitor. Hopefully this year will remain a safe and happy one for all visitors to this magical place.
Hike Safe and Have Fun!

Trail Conditions - April 30th, 2010:
Bright Angel and South Kaibab Trails are (finally) mostly snow and ice free, and the Nat'l Park Service (NPS) is no longer recommending cleats or crampons be worn. On the upper sections of North Kaibab (above Supai Tunnel) the NPS is still recommending crampons as there is still snow, ice, and rockfalls that have not yet been cleared from the trail. Although the snow is melting fast, traction devices are also still needed on Grandview and possibly on Tanner Trail.
Water Availability:
Drinking water is again available at Phantom Ranch and Bright Angel Campground as of April 22nd. The water pipeline break has been repaired. Along the Central Corridor (Bright Angel, South & North Kaibab Trails) water is only available at Indian Garden, Bright Angel Campground, Phantom Ranch, and Cottonwood Campground at this time. All other water sources are still turned off. Other ephemeral water sources are beginning to dry out, check with the Backcountry Information Center for up to date information on potential backcountry water availability.
North Rim Set to Open:
The gate for Route 67 (at Jacob Lake) to gain access to the North Rim will be unlocked and opened by the Arizona Dept. of Transportation on Saturday, May 15th, 2010 at 7:00 a.m. Concessions will open after 10:00 a.m., and lodging check-in will start at 4:00 p.m. North Rim facilities include lodging, food service, camper services, and the gas station.
Weather:
Cool temperature are still the norm, especially on the rim, with lows at night in the 20 degree range. Inner Canyon temps are mid-40's at night with daytime temps warming from the mid-60's and into the 90's by early May.

This winter the Grand Canyon received the most snow they have seen in the last quarter century. The Nat’l Park Service (NPS) at Grand Canyon is therefore still advising hikers to use trekking poles and traction devices, (cleats or crampons) while hiking the upper reaches of Bright Angel, South Kaibab and Grandview Trails. Tanner Trail isn’t too icy but the snow is still about three feet thick at the top. Most of the other trails along the South Rim are free enough of snow and ice to be reasonably navigated without cleats, these include New Hance, Hermit, and South Bass Trails. Access to South Bass Trailhead via Forest Road 328 is passable, but 4-wheel drive is recommended. The North Rim is still closed and snow on the North Kaibab Trail is many feet thick above Supai Tunnel.
Drinking water is currently not available at Bright Angel Campground or Phantom Ranch due to a pipeline break that occurred on April 13th. You should always carry a water treatment system of some kind when traveling the Inner Canyon, even when drinking water is supposed to be available, since the pipeline breaks quite often.
Inner Canyon temperatures are fluctuating wildly, (which is usual for spring in Northern Arizona), with daytime temps varying from the mid-60's to low 90's, and nighttime temps from the mid-40's to the mid-60's. A chance of showers is still around, (usually by May the showers stop and the heat begins to dominate).
Remember that parking at the canyon has changed. When entering the park visitors can no longer drive up to Mather Point (historically the first view many visitors would take in). Now you must park at Canyon View Information Plaza to walk over to Mather Point. The Info Plaza is also the bus hub for the Village Route and the Kaibab Trail Route shuttle buses.
