Old sign, predates ~2016 trail relocations that shortened the western end ~1 mi; actual distance now ~160 mi. Eastbound: ~160 miles covered from start at this point. 2018 trail reroute shortened all MPs <= 165 by 1 mile; sign reads 161 (Lake Fort Smith) but corrected validated_mp = 160.

Ben Branch signed OHT = 167.2 mi; sign distance is just under 2 mi by trail, so sign is at signed OHT ~165.2 mi. Cross-check: Woolum Ford (signed 164.0) is ~1.2 mi west (back toward Fort Smith) â€” consistent. Shortfall at BB 156.07 = 165.2 - 156.07 = +9.13 mi. Key finding: shortfall reached ~9.1 mi already by signed mile 165, stays flat ~9.1-9.7 through mile 325. Derived trail mileage ~165.2. Sign reads "Ben Branch 2 miles east"; Ben Branch has established signed MP 167.2, so this junction = 167.2 - 2.0 = 165.2. Consistent with GPS-to-signed delta at this trail segment.

We camped here not knowing he had trailed us the whole way. After dark we heard a kid across the lake shouting for Sam — back-and-forth hollering confirmed it was our dog, black, but Sam refused to swim the lake home and the kid was furious. About half an hour later a truck came up the old FS road nearby, an adult calling for Sam — then the truck drove away, silence, and Sam was gone. Good ending to a sad story. Named in Sam's honor.

White River Bridge (MP 254)
REF_WHITE_RIVER_BRIDGE | src=underwood_north_map | MP 254 per Underwood Graphics OHT North Map 4th Ed — marker shown at bridge midspan. Midpoint coordinates (36.223727, -92.299478) from visual reading of map, 2026-05-27. Two west-bank approach photos (20260502_120958, 20260502_121037, both MP 253.9) removed as duplicates; both GPS-tagged from western shore before bridge crossing. FarOut incorrectly labels this as 'Bridge over Buffalo River' — this is the White River. REF_INTERP_MP_254 removed (was interpolated from the wrong 253.9 west-bank bracket).
