The Appalachian Trail spans more than 2,000 miles across 14 states,
traversing woodlands and peaks from Springer Mountain in Georgia to
Mount Katahdin in Maine. It is one of the world’s longest continuous
footpaths, and each year thousands of individuals attempt to hike the
entire thing.
For any thru-hiker, making the trek is an accomplishment (fewer than
25 percent successfully complete the journey). But that’s especially
true if you’re blind. Which is why it’s so impressive that
Minneapolis-based attorney Mike Hanson set out along the Appalachian
Trail in the spring of 2010. Using only a GPS device and trekking poles,
the visually impaired Hanson plotted and completed the majority of the
Appalachian Trail without outside assistance, making an important point
about the power of technology and the independence of those without
sight.
Born in Madison, Wis., Hanson has been blind since birth. When he was
born prematurely, doctors gave him a high concentration of oxygen,
which damaged his retinas. Despite his impairment, Hanson is an avid
outdoorsman. As a child, his father’s stories about pheasant hunting in
rural South Dakota inspired him to seek out wilderness. Later on, Hanson
became a president of Capable Partners, a program designed to help
visually impaired individuals partake in hunting and fishing by
providing them with seeing partners as aides.
These experiences motivated him to pursue a long-distance hike, and
the AT seemed like a fitting goal. Many other visually impaired
individuals have completed similar journeys—among them Bill Irwin, who
hiked the AT with a guide dog—but few have employed GPS systems. Hanson
firmly believes that technology has the potential to change the way that
the visually impaired interact with the world, and he suspected that
using GPS to complete a big-ticket hike would help him prove his point.
For years, though, the technology was both too expensive and too limited
in its capabilities, which meant Hanson had to put his plans on hold.
Finally, in 2006, he noticed an increasing “availability of GPS that
you can use without sight.” Using his Nokia N82 cellphone, Hanson
downloaded a Loadstone GPS system, which is a free, open-source
application specifically designed to facilitate the mobility of blind
and visually impaired persons. The Loadstone GPS system allows its users
to search for points of interest in an area—such as grocery stores,
schools, and office buildings—and store those sites along with labels
for future use. With the addition of screen reader technology, the
Loadstone program can then provide oral instructions, letting a user
know when to turn and when a destination is nearby, all with the help of
clock-face directions. This data can later be shared online with other
users, leading to a crowdsourced database of sites. Unlike, say, your
iPhone’s navigation system, the Loadstone program does not have
extensive existing data points; however, the Loadstone program allows
visually impaired users to create their own personalized databases at a
low cost.

For his hike of the Appalachian Trail, however, Hanson needed more
detailed maps than crowdsourcing could provide. Hanson gathered data
from the Appalachian Trail Conservancy and other sources and converted
the information to the Loadstone GPS format on his phone. Hanson then
used tools on the Loadstone website—such as a route planner function—to
generate checkpoints along the trail. These locations—created by
entering geographical coordinates into the route planner—included things
like campsites, trailheads, and water sources. Most importantly, the
Loadstone tools allowed Hanson to store oral instructions along with
each point, which would be necessary on the trail.
Over the course of the next few years, Hanson continued to update his
GPS device while pushing himself into top physical shape. In true
sports montage fashion, Hanson did everything from hiking to lifting
weights to walking on a stair climber with a backpack. In 2007, Hanson
flew to Shenandoah National Park for a week and hiked part of the AT in
order to test his Loadstone system. The majority of his data proved to
be accurate, and each major point was within approximately 20 feet of
the GPS estimation. The test run also showed Hanson that he would need a
GPS receiver with longer battery life. Hanson replaced the
receiver—moving from a six-hour battery to a 32-hour battery—and began
to make final preparations for his hike.
On March 6, 2010, Hanson began his journey in Georgia, followed
closely by Gary Steffens, a filmmaker who decided to document the trek.
The two carried 40- to 50-pound backpacks filled with all of the
necessary materials, including first aid kits, tents, maps, and food.
For the majority of the trip, Hanson combined the use of his GPS with
the employment of trekking poles. At each checkpoint, Hanson would
listen to his GPS and gauge the distance and direction to the next site.
Then, intermittently along the trail, Hanson could verify his position
and maintain the correct orientation. While the GPS kept Hanson on track
in a macro sense, his trekking poles alerted him to smaller details,
such as obstacles and turns in the trail. Hanson’s sense of hearing
allowed him to locate water, campgrounds, and other important sites that
were not indicated on his maps.

Occasionally, dangerous weather and terrain proved challenging.
Before Hanson even set foot on the trail, a late spring blizzard
blanketed the AT with snow, making it difficult for Hanson to be sure he
was on the right path. Later, on Blood Mountain in Georgia, Hanson
explained, the men “faced heavy rain, strong winds, and slopes we had to
slide down.”
Although these setbacks slowed his pace—and forced him to skip a few
sections of the trail—Hanson remained steady and, in early October, he
began hiking the summit of Mount Katahdin in Maine, the final hurdle of
the AT thru-hike. With the help of two Maine residents he met that day,
Rita and Bain Pollard, Hanson found good foot- and hand-holds along the
Hunt Trail up Katahdin. On Oct. 2, 2010, Hanson and his companions
reached the top, the pinnacle of seven months and 1,700 miles of hard
work.
Reflecting upon the demanding trip, Hanson chooses to focus on its
broad implications rather than its personal significance. Although
Hanson has found success in a variety of roles—most recently as an
attorney—he recognizes that many people are unaware of the tools and
tactics that can allow blind people to accomplish a variety of tasks.
According to the American Foundation for the Blind, 70 percent of
legally blind individuals and 55 percent of visually impaired
individuals are unemployed. Hanson wants to inspire these individuals to
pursue grander goals, and he believes that “with the right technology,
one can do quite a few things.”

Unfortunately, although a lot of good technology exists, Hanson
explains that there is a “gap between what is available cost-effectively
… and what potential employers know about.” Many employers are wary of
hiring visually impaired individuals because they are unfamiliar with
their condition and may be misinformed about the cost of the
technologies required to address it. Even worse, many visually impaired
individuals are themselves unaware of the newest technologies.
Hanson is determined to address these issues, and hopes that his hike can help demonstrate the possibilities. He has written a book,
and is in the process of developing new GPS technology with his
business partner, Harlan Jacobs. Through their company, Wayfinder Angels
Corporation, the two are working to improve upon current products while
also raising awareness about tech aids in general.
As he plans his next adventure on the Pacific Crest Trail, Hanson
reminds us to never “give up on an idea because you don’t know how to
make it happen right now. Give it time … and just keep paying attention
to what is going on in terms of technology in the world around you.
Maybe not today, maybe not tomorrow, but at some point you’ll figure out
a way to make it happen.”
