Lesson 1: Precision Planning for Outdoor Leadership
The "As the Crow Flies" Trap
In 2018, a group attempted a 12-mile traverse in the North Cascades. They estimated 6 hours based on distance.
Reality:
4,500ft total elevation gain
Heavy "alder bashing" (bushwhacking)
Actual Time: 14 hours (Finished in dark)
Linear distance is a lie.
Terrain effort is the truth.
Digital Toolset
Map Layers
Combine USGS Topo, Shaded Relief, and Satellite imagery to "see" the ground before you arrive.
Slope Shading
Highlight steepness. Identify avalanche terrain (30°+) and impassable cliffs.
Offline Export
Digital plans are useless if not cached. Export GPX files and print physical backups.
Calculating Travel Time
Naismith's Rule
1
Allow 1 hour for every 3 miles (5 km) of forward travel.
2
Add 30 minutes for every 1,000 feet (300 m) of ascent.
"Go slow to go fast. Plan for the slowest person, not the fastest athlete."

Naismith's Rule Refresher
Horizontal: 1 hour per 3 miles (or 20 mins per mile)
Vertical: Add 30 minutes per 1,000 feet of ascent
Note: This is a base estimate for a moderately fit hiker with a pack. Adjustments for "Bushwhacking" (+50% to +100%) or "Steep Descent" (+10% for every 1000ft drop) are often necessary.
Part 1: Calculation Practice
Show your work in the space provided. Round to the nearest 5 minutes.
1. The High Divide Trail: 8.4 miles total distance with 2,400 feet of total elevation gain. What is the estimated travel time?
2. The Summit Push: 1.5 miles of steep trail with 1,800 feet of gain. Calculate the time. How does the "mph" feel here compared to a flat road?
3. The Off-Trail Shortcut: A 2-mile route through thick brush (double the time) with 500 feet of gain. Compare this to a 5-mile easy trail with 500 feet of gain. Which is faster? By how much?
Route Data Card: Digital Plan to Field Use
Leaders don't carry their full laptops. They carry "Data Cards" for quick reference. Using your assigned route in CalTopo/Gaia, fill out the data card for Leg 1 of your expedition.

Instructional Goals
This lesson moves students from intuitive "map reading" to quantitative "route planning." The goal is for students to recognize that distance is secondary to terrain effort. By the end of this session, students should be able to produce a data card that reflects the actual physical requirements of a wilderness leg.
Key Terms
• Naismith's Rule
• Slope Shading
• Catching Feature
• Handrail
• GPX File
Terrain Math Answer Key
1. The High Divide Trail (8.4 mi, 2,400ft gain)
- Distance: \( 8.4 \div 3 = 2.8 \) hours (168 mins)
- Gain: \( 2.4 \times 30 = 72 \) mins
- Total: 240 mins (4 hours, 0 mins)
2. The Summit Push (1.5 mi, 1,800ft gain)
- Distance: \( 1.5 \div 3 = 0.5 \) hours (30 mins)
- Gain: \( 1.8 \times 30 = 54 \) mins
- Total: 84 mins (1 hour, 24 mins)
Context: This is roughly 1 mph. Students should note that "fast" on a mountain is actually quite slow.
3. The Off-Trail Shortcut (2 mi brush, 500ft gain) vs. Easy Trail (5 mi, 500ft gain)
- Shortcut: \( (2 \div 3 = 40 \text{ mins}) \times 2 \text{ (brush penalty)} = 80 \text{ mins} + 15 \text{ mins gain} = \mathbf{95 \text{ mins}} \)
- Easy Trail: \( 5 \div 3 = 100 \text{ mins} + 15 \text{ mins gain} = \mathbf{115 \text{ mins}} \)
- Result: Shortcut is 20 minutes faster, but higher risk/effort.
Mapping Project Facilitation
Common Student Errors
Ignoring Micro-terrain: Digital maps smooth out small dips and bumps. Advise students to add 10% "wiggle room" to gain estimates.
Leg Length: Legs that are too long (5+ miles) are hard to manage. Recommend legs of 1.5 to 3 miles based on major topographic changes.
The "Case Study" Hook
When presenting the failed expedition slide, emphasize that the leaders were "fit and experienced" but failed because they relied on a single metric (distance). Ask students: "If you were the leader at hour 8 in the dark, what would your first priority be?"

Field Troubleshooting Scenario
Scenario: The Mystery Shift
You are leading a group in the Cascades. Your GPS says you are at your waypoint, but you are looking at a 200-foot cliff that isn't on the map. You check your settings and see your GPS is set to WGS84 but your printed paper map says NAD27 .

2. As the leader, what is your next action to regain navigational certainty?

Hook: The Coordinate Challenge
Hide 5 numbered tokens (or orange flags) around the campus/area. Provide each student team with one coordinate. They must input it as a Waypoint and navigate to within 3 meters.
The Goal
Demonstrate that "Precision" is different from "Context." They find the flag, but don't yet know the terrain between here and there.
Debrief Prompt
"Did you look at the screen the whole time or look at the ground? What did you almost trip over while looking at the satellite?"
Worksheet Answer Key (Part 3)
1. What is the immediate problem?
Datum Mismatch. WGS84 (the satellite standard) and NAD27 (the legacy US Geological Survey standard) use different models of the Earth's shape. This results in a "grid shift" that can be anywhere from 10m to 200m depending on the location.
2. Next Action for the Leader?
1. Stop movement. Do not follow the GPS into unsafe terrain.
2. Change GPS system settings to match the map (NAD27) immediately.
3. Re-verify position using visible topographic features (e.g., that 200ft cliff) on the paper map to "reset" navigational certainty.
Pro-Tip: UTM Zone Boundaries
If your expedition crosses a UTM zone boundary (e.g., from Zone 10 to Zone 11), Easting numbers will reset drastically. Warn students to check the Zone Number if their coordinates suddenly look "impossible" during a long-distance trek.

"For those who said NO-GO : How do you handle the potential resentment of the 3 members who want the summit?"
"Which FACETS trap is most active here? (Hint: Commitment and Social Proof)"
Leader Strategy
Guide students toward the "Pre-Mortem" technique: "If we go, and we get struck by lightning, how will we explain this decision to our families later?"
Goal: Shift from "Can we do it?" to "Should we do it?"
Historical Accident Analysis
Sample Case: Mount Hood (2002) - Multiple Fall
A large group was roped together. One person slipped, pulling 8 others down a steep snow slope. The "Expert Halo" trap was present as inexperienced hikers followed a popular but overconfident leader.
Trap: Expert Halo
Trap: Social Proof
Consequence: Critical
Sample Case: Lost Hiker - The "Shortcut"
A hiker left the trail to save 2 miles before dark. They became disoriented in thick brush and spent 3 days in the wild. The "Scarcity" of daylight forced a high-risk decision.
Trap: Scarcity
Trap: Commitment
Consequence: Major
Instructor Closing: Normalizing the "No"
End the lesson by emphasizing that a successful trip is one where everyone comes home. The summit is optional; returning is mandatory. Ask students to practice one phrase of "No-Go" communication for the field:
The Transparent Leader
"I'm noticing the clouds are building faster than we expected. To stay in our safety margin, we need to turn around now."
The Democratic Leader
"Looking at our turnaround time, we have 5 minutes left. If we don't hit the summit in 5, what's the group's bail-out plan?"

Leave No Trace in a Crisis
Does safety override the environment? Sometimes.
Use durable surfaces for shelters, even if it means more work.
Minimize ground disturbance. A signal fire is a high-impact choice.
Ethical Rule: Safety first, but don't cause a second emergency (e.g., a forest fire).
The "Stay Put" Ethic
Search & Rescue is easier when the target isn't moving. Staying put is both safer for you AND less impactful on the land.

Scenario Alpha
The Lower Leg Injury
Situation: 5 miles from the trailhead. A student slips on a wet root. Audible 'snap'. They cannot bear weight. It is 3:00 PM; sunset is at 5:30 PM. Weather is dropping to 40°F.
Primary Task:
Determine if this is a self-evac or a SAR call. Draft the initial SOS message for your satellite device.
Scenario Bravo
The Separation
Situation: During a bathroom break, one student wanders off. It has been 20 minutes since they were last seen. The terrain is dense forest with multiple social trails.
Primary Task:
Establish a "Point Hasty" search. When do you stop searching and call for professional help?
Scenario Charlie
The Ridge Exposure
Situation: Your group is on an exposed ridge. A sudden thunderhead develops. Lightning strikes a peak 1 mile away. Hair is standing on end. Nearest trees are 800 vertical feet below.
Primary Task:
Apply the 30/30 rule. Position the group for maximum safety. What LNT principles might you break here?
Scenario Delta
The Environmental Crisis
Situation: Temperature is 95°F. A student stops sweating, becomes confused, and skin is hot to the touch. You are in a desert canyon with no shade.
Primary Task:
Apply the "Rule of 3s". How do you create shade where there is none? What is your water management plan?
Facilitator Note: "The Overwhelmed Leader"
During these simulations, watch for students who try to do everything themselves. Encourage them to delegate (e.g., "You, get the InReach. You, start a patient assessment. You, check the map for the nearest LZ."). Leadership in a crisis is about managing resources, not just performing first aid.

Simulation Injects Resource The "Inject" Deck
Lesson 5: Field Leadership Simulation
Instructor Resource
"Injects" are planned disruptions designed to test a leader's ability to adapt. Introduce these unexpectedly during the hike. Observe how the current Leader of the Day (LOD) reacts, communicates, and prioritizes.
Inject 01: Environmental Shift
"The Storm Warning"
Tell the LOD: "You just received a weather alert on your InReach. A severe thunderstorm with lightning is expected to hit this ridge in 45 minutes."
Look For:
Does the leader speed up or turn around? Do they check the map for lower ground immediately?
Style Check:
This requires Directive leadership. If they are too consultative, the group stays in the 'red zone'.
Inject 02: Technical Failure
"The Dead Battery"
Confiscate the LOD's GPS unit and primary paper map. Tell them: "Your electronics have failed due to cold, and your map just blew off a cliff."
Look For:
Does the leader utilize group resources (other students' gear)? Do they stop to regain situational awareness?
Style Check:
This is a great moment for Delegative leadership—assigning others to check their backups.
Inject 03: The Human Factor
"The Complacent Navigator"
Secretly tell one student to intentionally lead the group 50 yards off-trail or take a wrong turn at a junction when the LOD isn't looking.
Look For:
How long does it take for the LOD to notice? Do they trust the group too much ("Expert Halo") or verify their own location?
Style Check:
Requires Consultative leadership to "reset" the group's navigation together.
Master Instructor Strategy
Safety First: Ensure that no inject actually places the students in real danger. You are a "shadow leader"—always aware of the real situation even while playing the "simulated" one.
Normalizing Failure: If an LOD fails to handle an inject well, emphasize that this is the best possible place to fail. Use it as a powerful teaching moment in the AAR (After Action Review).
