What to check first (do this before you drive out)

Before you even think about heading into the backcountry, especially if you’re going solo, there are a few key things to get squared away. This isn’t just about having fun; it’s about being prepared and responsible.

• Land manager / legality: Know who manages the land you’re entering. For areas like the Flat Tops Wilderness, it’s typically the U.S. Forest Service (USFS). Check their website for any specific regulations, permit requirements, or area closures. Ignorance isn’t a good excuse when you’re out there.

• Access/road conditions: Get the lowdown on how to get there. Wilderness areas often have rough roads, sometimes requiring high clearance or 4WD. Check recent reports or call the local ranger district to see if roads are passable. A Subaru might be fine for some trails, but others will chew it up.

• Fire restrictions + weather + wind: This is critical. Wildfire is a serious threat, and conditions can change fast. Always check current fire restrictions before you go. Look at the weather forecast for the entire duration of your trip, not just the drive in. Don’t forget wind – it can make a chill day brutal and increase fire danger.

• Water plan + waste plan (Leave No Trace): Have a solid plan for water. Will you carry it all? Filter it? Know your water sources and have a reliable purification method. Equally important is your waste plan. Pack it in, pack it out. This includes all trash, food scraps, and human waste if necessary. Stick to LNT principles.

• Safety (wildlife, distance to help, comms): Be aware of the wildlife in the area. Know how to store food properly to avoid attracting bears. Understand how far you are from the nearest help and what your communication options are. Cell service is a luxury in most wilderness areas. Consider a satellite messenger.

Step-by-step (field workflow)

When you’re actually out in the field, a methodical approach keeps you safe and helps you enjoy the experience. This is about being present and aware.

• Step 1: Arrive and Orient.
• What to do: Park your vehicle securely and take a moment to look around.
• What “good” looks like: You’ve confirmed your location against your map and GPS. You know your starting point.
• Common mistake: Rushing out of the car without checking your surroundings or confirming your exact parking spot. This can lead to getting turned around before you even start.

• Step 2: Gear Check.
• What to do: Do a quick but thorough check of your pack and essential gear.
• What “good” looks like: All straps are secure, water bottles are full, and your navigation tools are accessible.
• Common mistake: Assuming everything is fine because you packed it. Forgetting to zip up a pocket or secure a critical item.

• Step 3: Navigation Setup.
• What to do: Get your map and compass or GPS device ready.
• What “good” looks like: You know your planned route and have a clear understanding of your first few waypoints.
• Common mistake: Relying solely on a phone app without a backup or understanding how to use a physical map and compass.

• Step 4: Leave Your Itinerary.
• What to do: Ensure someone reliable has your detailed itinerary, including your planned route, expected return time, and emergency contact info.
• What “good” looks like: Your contact person knows exactly where you should be and when you should be back.
• Common mistake: Telling a friend “I’m going camping” without specific details. This makes a search impossible if something goes wrong.

• Step 5: Initial Site Assessment.
• What to do: As you hike, note potential campsites, water sources, and hazards.
• What “good” looks like: You’re mentally cataloging options and risks as you move.
• Common mistake: Tunnel vision on just reaching your destination, ignoring the journey and potential opportunities or dangers.

• Step 6: Water Source Identification.
• What to do: Locate reliable water sources along your route.
• What “good” looks like: You know where you can refill your water supply safely and efficiently.
• Common mistake: Assuming a stream shown on an old map will still be flowing. Water levels fluctuate.

• Step 7: Camp Setup (if applicable).
• What to do: Choose a durable surface away from water sources and set up your shelter.
• What “good” looks like: Your tent is pitched securely, and your cooking area is a safe distance from your sleeping area.
• Common mistake: Camping too close to water, which degrades vegetation and can contaminate water sources.

• Step 8: Food Storage.
• What to do: Properly store all food and scented items away from your tent.
• What “good” looks like: Your food is in a bear canister or properly hung, well away from your sleeping area.
• Common mistake: Leaving food in your tent or car, which is an invitation for unwanted visitors.

• Step 9: Situational Awareness.
• What to do: Continuously scan your surroundings for changes in weather, animal signs, or potential hazards.
• What “good” looks like: You’re attuned to your environment, noticing subtle shifts.
• Common mistake: Getting lost in your own thoughts or music, missing important cues from nature.

• Step 10: Trail Marking (if needed).
• What to do: If venturing off-trail or in complex terrain, leave subtle, natural markers.
• What “good” looks like: You can retrace your steps if necessary, using minimal impact markers.
• Common mistake: Relying on cairns that others might move or not seeing them clearly.

• Step 11: Waste Management.
• What to do: Pack out everything you pack in. Properly dispose of human waste if necessary.
• What “good” looks like: Your campsite is cleaner than you found it.
• Common mistake: Burying trash or leaving food scraps, which harms wildlife and pollutes the environment.

• Step 12: Pre-Departure Check.
• What to do: Before leaving camp or heading home, do a final sweep of your area.
• What “good” looks like: You’ve left no trace and are confident you haven’t forgotten anything.
• Common mistake: Leaving gear behind, especially small items that can be mistaken for trash.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Inadequate research of the area	Getting lost, encountering unexpected hazards, violating regulations.	Thoroughly research the land manager, permits, road conditions, and local rules.
Insufficient or faulty gear	Exposure, inability to handle emergencies, discomfort, injury.	Test your gear before you go. Pack essentials and have backups for critical items.
Poor navigation skills	Getting lost, spending unnecessary time searching for the trail, increased risk.	Practice with map and compass. Carry a GPS device with backup batteries.
Not informing anyone of your plans	Delayed or impossible search efforts if you go missing.	Leave a detailed itinerary with a trusted contact.
Underestimating weather	Hypothermia, heatstroke, dangerous conditions for travel.	Check forecasts diligently and pack for a wide range of conditions.
Improper food storage	Attracting wildlife, potential encounters, damage to gear.	Use bear canisters or proper hanging techniques. Keep food away from sleeping areas.
Ignoring Leave No Trace principles	Environmental degradation, impact on future visitors, harm to wildlife.	Pack out all trash. Minimize campfire impacts. Stay on trails.
Overconfidence in solo trips	Taking unnecessary risks, not having backup in an emergency.	Be extra cautious. Know your limits and have robust safety protocols.
Not checking fire restrictions	Starting an illegal fire, contributing to wildfires, facing fines.	Always verify current fire restrictions with the land management agency.
Assuming water sources are safe	Waterborne illnesses, dehydration if sources are dry.	Treat all water. Know your water sources and have multiple options.
Poor physical conditioning	Fatigue, injury, inability to complete the trip, increased risk.	Train appropriately for the demands of your trip.
Not having a communication plan	Inability to call for help in an emergency.	Carry a satellite messenger or personal locator beacon (PLB) in areas with no cell service.

Decision rules (simple if/then)

• If the weather forecast shows a high chance of thunderstorms, then postpone your trip or have a solid plan for shelter and lightning safety because thunderstorms in the mountains can be deadly.
• If you are unsure about road conditions, then call the local ranger district before you leave because a 2WD vehicle can get stuck on a road that looks fine on paper.
• If you see fresh animal tracks or scat, then be extra aware of your surroundings and make noise because you are in their territory.
• If your map shows a reliable water source but it’s dry, then consult your GPS for alternative sources or be prepared to backtrack because relying on outdated information can be dangerous.
• If you are feeling fatigued or unwell, then consider turning back because pushing too hard can lead to mistakes and injuries.
• If you encounter a trail closure or hazard, then find an alternative route or turn around and report it because safety and park rules come first.
• If you are in an area with known bear activity, then always use a bear canister and keep your camp clean because it protects both you and the bears.
• If you plan to go off-trail, then ensure you have advanced navigation skills and tools because it significantly increases your risk of getting lost.
• If you are running low on water and your planned refill spot is dry, then conserve what you have and prioritize finding a new source immediately because dehydration sets in fast.
• If you are solo and something feels off about the environment or your own condition, then trust your gut and consider ending the trip early because there’s no shame in prioritizing safety.
• If you are planning to build a campfire, then always check for current fire restrictions and have water and a shovel nearby because escaped campfires are devastating.
• If you are in a wilderness area, then remember that “help” is far away, so be extra prepared for self-sufficiency because you are your own primary rescuer.
