How To: Manage the Risks of River/Creek Crossings

As the weather gets warmer and winter snow melts away, more of us are heading outside. And as the snow melts, it leaves us with a sometimes a challenging obstacle: water. In the Cascades, it doesn't matter if you are a hiker, scrambler, or climber, eventually you'll have to deal with a water crossing. It could be a small trickle or a rushing river. It's not a matter of if, but when, you'll encounter this obstacle.

Historical Perspective

A few years ago, a Mountaineers group was headed to climb Sahale Peak. The team was crossing a small drainage in the area between Midas and Morning Star Creek - two of the main creeks that flow out of the Quien Sabe Glacier below Sahale - when one of the climbers slipped and hit her face on the rock in the creek. This caused a small laceration, just under the right eye, and swelling around the area, as well as a headache, slight dizziness, and swelling. The trip leader decided to cancel the climb and turn around at this time.  The group headed back to the cars and the injured climber was taken to the hospital for medical evaluation. Luckily, she sustained no fractures or head injury, but she did have a nasty black eye. 

This incident shows how something seemingly simple, like crossing a small trickle of water, can be detrimental to the success of a trip.

Avoiding Hazards

Many different hazards are involved in water crossings: slippery, moss covered rocks, swift currents, soggy boots, and cold feet. If you do fall in, you have soaked clothing and gear, the risk of hypothermia, potential projectiles in the water like logs and boulders, and much more.

Here are some tips to reduce your chances of ending up soaked and needing to cancel the rest of your trip:

• Never try to cross a major stream if you are alone. It only takes 2" of water to drown. The climber in the incident above could have easily been knocked unconscious, and if there was no one to help her up, it could have been a different outcome.
   
• Quickly search both upstream and downstream for a way to cross without having to ford the water. Look for downed logs, closely spaced stones and boulders, or narrow points in the waterway. Be sure to keep in mind the ability and experience levels of everyone in your group.

If you find possible logs or stepping stones, consider:  

• Will it hold you? If you are considering a log, is it strong enough to hold your weight as you cross, or is it rotten and will break once you are half-way out? Is it wide enough to get good foot placements? Are there branches sticking up in your way? If you are considering stones, are they sturdy and solid, or are they going to shift under your weight and dump you in the water?
• What is the surface like? Does that log have rough, textured bark that will give you good traction, or is the bark peeled away showing damp, slick hardwood? If you are unsure of the footing, but the log seems strong enough, one alternative is to butt-scooch along the log. Are those stepping stones covered in slick moss, or do they have good texture?  
• Be particularly cautious of log jams. They might seem like a solid option, but the logs can easily shift and throw you off balance and into the water. Now you are in even bigger danger of getting caught underwater by one of the logs.

Regardless of how you have to cross - whether it be logs, stepping stones, or just fording the water - take a minute to look downstream of your crossing point and examine the hazards you could encounter if you fall in. Is there a large waterfall you could get swept over? Maybe a downed tree or log jam that you could get caught in or some large boulders you could hit. If anything like this poses a danger, re-evaluate your crossing point.

Picking the best spot

If your only option is to ford the water, follow these steps:

1. Look for the shallowest, slowest running section. This is usually also a wider section of the waterway.
2. Assess the water's speed by tossing in sticks, leaves, or grass into the water. If there is debris actively floating down the water (evidence of flooding) or the sound of tumbling rocks can be heard underwater (evidence of fast-moving water), the crossing should be abandoned. 
3. Keep in mind the the physical stature of other people in your group. Two feet of water could be less than knee-deep if you are 6'6" tall. But it could be mid-thigh deep for someone under 5' tall, and that makes it much more challenging.
4. Look at the bank on the other side. Avoid steep banks as this not only indicates a challenge exiting the water, but that steepness could continue dramatically down and create a deep hole with fast-moving water.
5. If possible, plan to cross early in the morning. Many of the waterways in the Cascades are directly fed by snow-melt. After a cool night, there won't be as much melting and the water level will be lower. On the flipside, after a long, hot summer day (or even a warm spring rain) there will have been a lot of melting and all that water will be rushing through the streams at a higher overall level that afternoon, making them both deeper and faster flowing.

Staying Dry & Avoiding Injuries

Once you've chosen your place to ford the water, follow these tips to stay dry and avoid injuries:

• If you have sandals with an ankle strap (like Chacos or Tevas) change into those. Avoid flip-flops as the loose heels can get caught in the current and make you lose your balance.  
• If you don't have alternate footwear, at least take your socks off and put your bare feet back in your boots. That way, you can put your dry socks back on after crossing and they can start to absorb some of that water in your boots.
• Do not cross in just your bare feet. Unknown hazards in the water, like sharp sticks, rocks, possibly even fishhooks, could injure you. Your bare feet are a poor substitute for the traction provided by the soles of your boots.
• Take off extra layers and pack them in the most water-proof thing you have. I always carry one or two extra heavy-duty trashbags in my pack. Take that warm puffy off and wrap it up the best you can. You'll want it once you get to the other side!  Roll up your pant-legs, or ditch your pants altogether.
• Undo your waist-belt and sternum straps on your backpack and loosen your shoulder straps. If you do fall in, this will allow you to easily get your pack off.

Crossing Methods

• If you are crossing the water one at a time, use your trekking poles, ice axe, or downed tree limbs for stabilization. 
• Cautiously enter the water and face upstream. If you only have one pole or limb to help you, hold it with both hands in front of you (upstream) to form a tripod with it and your legs. Lean on the pole as third leg as you shuffle-step across, keeping two points of contact at all times. If you have two poles or limbs, you can use the one in your leading hand to probe along the way and feel for submerged obstacles or hidden holes.  
• Another method is to cross as a group using the "mutual support method." There are two options for this - in the first option, everyone should face upstream and hold on to the shoulders or backpack of the person in front of them (front person can have a pole or limb). As a group, shuffle step across the water, using each other for support and stability.  
• Another option is for everyone to face the opposite bank and move together as a unit. In this method, keep the waist-belt of your backpack buckled. Insert your arms between your neighbors' back and their pack, and grab their waist-belt on the opposite hip. In both scenarios, the most upstream person should be strong, then the second person should be the strongest and/or most experienced. The person on the other end should also be strong, and then all other members sandwiched in the middle. End people can also have poles for extra stability. Don't break formation until everyone is out of the water.

Regardless of which method you use, don't fight the current or try to go straight across the water. Instead, with each step move diagonally downstream as you make your way across.

If you do fall in, try to stand back up as quick as possible before your backpack gets too waterlogged. If you are swept downstream, get out of your pack but try to keep hold of it and use it for flotation. Try to position yourself face up with your feet downstream of you. Only try to stand up once you can touch the bottom in shallow water. Editor's Note: Be aware of the dangers of foot entrapment anytime you stand up in moving water. 

Once you've made it across, wring out your damp clothes and use a pack towel to dry off as much as you can. If available, switch into dry clothes. Put on an extra insulating layer to help keep in what little body heat you have. Pop a quick bite of food in your mouth and start hiking to generate some more warmth.

Take every water crossing seriously. Always ask yourself, "Do we need to cross? Where do we cross? How do we cross?" Even with all of these tips, be sure to keep in mind that if there is any doubt, not crossing at all is the best option.
