This
map shows how close the Beaver Brook trail (BB) gets to where Amy's car was found (west of Tunnel #3 near Elk Creek).
Amy's car was found near
mile marker 264.
Trailhead at Windy Saddle for Beaver Brook trail that was blocked off this morning.
If Amy's car was parked east of Tunnel #2, the through hike might be more plausible. Starting here would not require crossing the creek which was near flood stage when she disappeared. But how did she plan on getting back to her car?
If someone dropped off her car to mislead investigators, it's also a problem. Geting back to town would almost require a second driver.
