Overland Trails Synthesis — 6 Trails, Distance, Scale, and Indigenous-Homeland Mapping

Sovereignty Promise. Recall: lessons 4 (Lewis & Clark route), 13 (Gold Rush), 17 (Mormon Trail) all involve overland routes. Today we synthesize.

• Recall prior lessons
• Set synthesis goal

Direct teach 6 trails: (1) Lewis and Clark route 1804-1806, ~8,000 miles round trip; (2) Santa Fe Trail 1821-1880, Independence MO to Santa Fe NM, ~900 miles; (3) Oregon Trail 1841-1869, Independence MO to Oregon City OR, ~2,170 miles, ~400,000 emigrants; (4) California Trail 1840s, branching from Oregon Trail at Fort Hall ID, to Sacramento CA; (5) Mormon Trail 1846-1869, Nauvoo IL to Salt Lake Valley UT, ~1,300 miles; (6) Pony Express 1860-1861, St. Joseph MO to Sacramento CA in 10 days using ~190 stations and ~80 riders. All 6 trails crossed Indigenous-nation homelands. Trails NPS-administered as National Historic Trails today (most).

• Distance and time matter — the trails were not 'short trips'; they were 4-6 month journeys.

  model 2,170 miles from Independence MO to Oregon City OR. Wagon parties traveled 4-6 months. Compute: 2170 miles ÷ 120 days ≈ 18 miles per day on average. Some days more, some less, depending on terrain.

  prompt How far is the Oregon Trail?

• Which trail is longest?
• Which trail had the largest number of emigrants?
• Name 2 trails that started at Independence MO.

MG-2 trail overlays are themselves sources — created by NPS Historic Trail Office. Note that pony express route is best documented; women's diary sources cluster on Oregon and California trails.

• 6-trail overlay placement on MG-2 with scale-ruler distance computation.

  scaffold Use scale ruler; check 2 sample distances.
• Indigenous-homeland identification: for each trail, name 2 Indigenous nations whose homelands were crossed.

  scaffold Use Indigenous-homelands overlay.

M-4-S-GEO-18-A Map

6 transparent overlay sheets, each showing one trail route in distinct color on a base US 50-state outline matching MG-2 scale. Lewis and Clark = orange; Santa Fe = green; Oregon = brown; California = yellow; Mormon = purple; Pony Express = red. Each sheet labels termini, key landmarks, distance, and Indigenous-nation homelands crossed.

MG-2 Map

US 50-State Physical and Political Map (tactile-relief version available): full continental US plus Alaska and Hawaii insets; all 50 state outlines in faint gray with capital-city dots and state-name labels in 12pt; major landforms in raised-relief tactile version (Appalachians, Rockies, Cascades, Sierra Nevada, Coastal Range, Ozarks, Great Smoky Mountains); major rivers (Mississippi/Missouri/Ohio/Columbia/Colorado/Rio Grande/Hudson) in blue; Great Lakes labeled (Superior/Michigan/Huron/Erie/Ontario); Great Plains shaded; deserts (Mojave/Sonoran/Great Basin) shaded; climate zones lightly indicated via 5 color washes; 5 region-boundary lines overlaid (Northeast / Southeast / Midwest / Southwest / West) with Pacific Northwest sub-region and Alaska/Hawaii separately. Translucent overlay layer (removable): historic Indigenous-homelands map circa 1500 CE based on cartographic work by Native Land Digital (native-land.ca, used with permission) showing 100+ nation-names across the continent. Style: cartographic accuracy, child-readable labels, tactile-raised landforms.

M-4-S-GEO-18-B Manipulative Physical / non-image

Cardstock or plastic scale ruler matching MG-2's scale (1 inch = 200 miles for the main 50-state view; adjusted for AK/HI insets). Marked with mile increments. Children measure trail lengths against MG-2.
