I'm assuming it's in the ESRI .E00 ancient exchange format. You actually
have to go .E00->arc info->shp->osm I'm working on automating a toolchain to
spit out .shp files (because those are the most useful to me) and then
another bulk importing toolchain from shp->osm->api

To get you started though, esri has a program called import71.exe that will
convert e00 to arc info coverages I just run it from within a windows
virtual machine in linux. There is also
http://avce00.maptools.org/avce00/index.html which I will be attempting to
use to automate it.

To get from arc info coverages to shp files you need gdal [1], and proj.4
[2] and I went the python route so you need the python bindings [3] If
you're on windows, Leszek from freegeographytools.com has made a GUI to gdal
[4] which I've only used a few times. I suggest not getting FWTools and
instead setup everything by hand seperately. Then you can use one of the
various python or perl (no ruby scripts?) shp -> osm scripts  (or one of the
java programs).

Anyway, seeing that what mostly exists for the Badlands is from Tiger

My take on the problem with Olympic National Park (where there is pretty
good
data) is to just import all of the park trails (which I found the
National Forest Service has but NPS doesn't) and then as I'm hiking
around and working in the park I'll check
the trails. From a quick look at the Yahoo! aerial photography the park data
appears to be pretty much spot on (barring washouts, avalanches etc) so I'm
not foreseeing any problems with a bulk upload. For areas where the USGS
maps are better (they are notoriously awful here) you can always use the
USGS WMS server to get in preliminary trails. I do definitely like the idea
of a bunch of hikers ambling around our national parks with gps units and
going to town on OSM, though.

The NPS has some GIS data available at...

I've just created a NPS Data Sources page on the wiki [a] with
blatant plagiarism from the US NFS wiki page [b]. You may want to create a
mapping parties section on there. In addition to the NPS Data Store many
universities catalog US Govt. GIS data so checking for 'University of ____
GIS "data store"|clearinghouse badlands trails' in google will often turn up
some data.
