Johnny “Foon” Chilton was mentioned as a big mountain pioneer of the area in this article explaining how Google Earth has become the new tool in sourcing out places to ride!

“Now a Pemberton local, Dave Basterrechea first came to Pemby from Idaho to film
in the Lone Goat area with the late, legendary, local guide Eric Smith in 1996. Back
then, local ski mountaineers such as Eric Pehota and Johnny “Foon” Chilton had
been putting down serious lines in the area, but only a handful of touring diehards
and avalanche technicians were regularly tapping in the Pemberton backcountry.
During that Adventurescope era, pro shreds such as Shin Campos, Marc Morisset,
Kevin Young, Scott Newsome, Mikey Orr and photographer Kurtis Croy started poking
around Pemberton’s expansive terrain with higher-horsepower snowmobiles
and cheap heli drops. Soon freestyle pioneers such as Sean Kearns and Devun Walsh
also started secretly pushing north to film while underground riders such as Mark
Usher and John Greenglass began getting out after larger lines with big drops.
When Dave and his wife relocated permanently in 2005, moving his
snowmobile rack business to town, gritty Pemberton was in the process of
incubating an underground scene with freeriders, ski and shred, such as
Kevin Smith, JD Hare, Joe Lax, Chris Sanchez, the Huffman brothers and the
Davies brothers riding big local lines far from the media limelight.
In the midst of this anonymity, Dave B. and Joe Lax started stalking bigger
lines in the understated fashion. The list of accomplishment, between the two
of them, grew to include lines such as descents on Currie, Meager and Pylon, the
north chute on Samson, sketchy rides deep in the Tantalus and, last winter, Dave’s
first descent of The Fine Line on Currie. Lax laid claim to the first-ever descent
of Dragon Slayer and Dave B topped his own line list by following Jonaven Moore
down the infamous Papa Jordan line up the Rutherford. And it was all for the rush.
“That feeling of riding new terrain is hard to beat,” explains Dave B. “You can ride
the same thing over and over and its fun, but if you find something new, there is something
about it that is always better—especially if you figured out how to get in there. “
Before Google Earth, Dave remembers, it was a tedious process of trial and error
that resulted in shut downs and dead ends more often than glorious lines. Google
Earth was a godsend, making it possible to link together drainages, unlock whole
new zones and visualize alpine-style missions—like the first snowboard descent on
Plinth he rode four years back with two of his mentors, American expats Jon Johnson
and the late Jack Hannan. But this exhaustive style is not for the faint of heart.”
