First, for the mileage calculator to work, you have to
current mileage total appears in the Status Bar, you need
to make sure that you have that turned on as part of having
When you put your mouse over one of the marked distances,
its background should turn pink, and a description of
its path should appear at the bottom of your browser
(in the status line). If the trail has an official name,
I have used that. If not, I have made one up, based on
whatever feature (or whim) I can identify in the area.
The colors I have used for the trails generally don't mean
much. However, occasionally the blaze for the trail is
a good color, so I will use that. For instance, a trail
named "The Orange Trail" with orange blazes will probably
appear orange on the map. White, not so much. The Buckeye Trail
is always in that slate color (but just because a trail is
shown in slate does not necessarily mean it is the Buckeye
The distances were gotten by measuring (more or less) along
the maps themselves. Naturally, this has some inaccuracies.
The trail may not be exactly where I drew it (although I have
taken some care in trying to use topographic features to
locate the exact route of each trail). The trail may have made
many small jogs that simply do not show up at the detail of
the map. Thus, if anything, my suspicion is that the final
calculated distances may underestimate the actual distance.
I once had a co-hiker use his GPS system to measure a route
we took. His answer was about 80% less than mine (which I don't
believe). But, again, we don't know how often the GPS took
its samples, so it, too, could have missed various twists
Probably the only way to get better accuracy is to hike the
trails with a distance wheel, but even that would have troubles:
should you really count rolling over every rock? Regardless,
the mileage distances given seem to agree fairly well with
the "officially" published distances."
In general, if a path on the mileage calculator does not have
a mileage next to it, that means that I have not actually
hiked the trail (and if there is a mileage, it
means I have hiked that leg). In that case,
I got the route of the path from some book or brochure, and
am not personally aware of exactly what route (or distance)
is uses. I will only put a mileage into the calculator when
I am reasonably sure of the route and distance. (However, an
un-distanced trail could also mean that I've hiked the trail,
but just haven't gotten around to adding that distance to
the mileage calculator yet).
Many of the trails shown are old and/or obscure. The official
trails are usually well-marked, but for the lesser ones, you
may have to look carefully to find them, or use topographic
features to help you locate where they are. Sometimes I
will bushwack. A particular bushwack I find myself using fairly
often will be marked with a dotted, colored line.
Finally, the distances on the maps might change over time.
If I hike the trail and decide that I have not located it
properly, I may redraw the trail, and recalculate the distance.
Usually such a change is pretty small (in the hundredths of
