ENO RIVER STATE PARK TRAIL-FOOT-MINUTES CALCULATION

Calculated at: September 26, 2026, 11:44 p.m. EDT
UTC timestamp: 2026-09-27T03:44:50.942Z

Definition
----------
One trail-foot-minute means one linear foot of trail closed for one minute.

CURRENTLY CLOSED TRAILS
-----------------------
Pea Creek Trail:
  1.3 miles, closed since June 1, 2020

Trails closed since July 5, 2025:
  Bobbitt Hole Trail: 1.65 miles
  Cole Mill Trail: 1.2 miles
  Cox Mountain Trail: 4.1 miles
  Fanny's Ford Trail: 1.0 mile
  Holden Mill Trail - Riverside Section: 1.2 miles
  Combined: 9.15 miles

Total currently closed length:
  1.3 + 9.15 = 10.45 miles

Current trail-foot-minutes at the calculation timestamp:
  54,058,249,344

Current rate of increase:
  10.45 miles x 5,280 feet = 55,176 trail-foot-minutes per minute

KNOWN COMPLETED CLOSURES
------------------------
Closed July 5, 2025, through September 8, 2025:
  Buckquarter Creek Trail: 1.5 miles
  Ridge Trail: 0.4 miles
  Fieldstone Trail: 0.6 miles

Closed July 5, 2025, through September 29, 2025:
  Holden Mill Trail - Upland Section: 1.6 miles

Closed July 5, 2025, through March 5, 2026:
  Dunnagan Trail: 1.9 miles

Trail-foot-minutes from these completed closures:
  5,792,719,680

DOCUMENTED TOTAL
----------------
Currently closed trails:     54,058,249,344
Known completed closures:  +  5,792,719,680
                              --------------
Documented total:             59,850,969,024 trail-foot-minutes

The defensible summary is: more than 59.85 billion trail-foot-minutes of
documented closure since Pea Creek Trail closed.

METHOD AND ASSUMPTIONS
----------------------
For each closure:

  trail-foot-minutes = trail miles x 5,280 x elapsed minutes

Because the records provide dates but not times, each closure and reopening
was treated as occurring at midnight Eastern Time on the listed date. Elapsed
minutes were rounded down to the last complete minute.

LIMITATIONS
-----------
This is not a complete historical total.

* The listed Laurel Bluffs closure from Pleasant Green does not have a matching
  segment length in the cited trail-status source, so it is omitted.
* The available records do not provide complete lengths and reopening dates for
  every trail affected by the park-wide closure after Tropical Storm Chantal.
* Sources disagree on some trail lengths. The completed-closure subtotal uses
  the HelloEno values available during this calculation. The September 2026
  State Parks CSV instead lists Ridge Trail as 1.27 miles, Dunnagan Trail as
  1.8 miles, and the full Holden Mill loop as 2.6 miles without separately
  identifying the closed upland and riverside distances.
