| Description: |
| West Alt One, our designation, on
on the east side of Highway #3 west of Behchoko and accessed
through a gravel pit road to site. Horizon is clear above +1º at
C3-C4. Site consists of gravel till with cover and low
brush. There are no services. |
View from West Alt One towards the northwest. The site
is perched on a ledge overlooking an old quarry sit(?). The
distance trees screen the site from Highway #3. The horizon
is clear above 1º. |
There is plenty of room for observers and equipment at this
site. The gravel till has cover and low brush. Be
careful not to step on bison scat.
|
West Alt One alternate site is accessed on the southeast of Highway #3
(picture from early spring.)
|
After entering the gravel pan turn left to the northeast and
follow the trail to the site. Use your GPS if needed. |
