M1 R2: 35 nadir + 21 oblique + 9 low detail photos. Original route estimate: 19:51; review battery reserve. R2 removes rejected ISO setup; camera capture check pending. All photo stops north of the M0 flight line. South–west–north U; travel at 20 m above launch. Porch/gazebo drops: 4.5 m and 2.8 m, then climb. Tree clearance ≥22.8 ft in the preserved LiDAR. Confirm the assumed M0 launch and current obstacles. Rear deck, green strip, hill and trees included. Hot tub: out-of-frame location placeholder; size unmeasured.
USGS 3DEP bare-earth DEM and raw point returns from the 2018–19 Southwest Colorado QL2 LiDAR (Quantum Spatial for USGS). At 146 Alpine, a 1 m local return surface supplies the measured roof and dominant north-side tree crown; elsewhere the DEM is resampled to 4–5 m. Imagery Archuleta County 2025 aerial (EagleView, via the county Portico parcel viewer). Footprints and roads OpenStreetMap. Parcel lines are Archuleta County GIS, shown exactly as published; because the county fabric is offset from the ground by a different amount on each block, the aerial photo, LiDAR terrain, building footprints and roads have been shifted block by block (up to 6 m east and 10 m north at 146 Alpine, blended over 25 m) to fit the parcel lines, so positions here are good to about ±3 m and are not a survey. Optional trees outside 146 are inferred from imagery and their types and heights are estimates.
