Topography of the ascending grade: a short 50 meter stretch of a slight grade uphill before the portage levels out and begins slow down-grade to the Longer Lake side. Portage is generally firm ground through grass and hard packed earth – there are a few rough boardwalks over the wet or muddy section closer to the Longer Lake side. No steep rises, portage is well maintained.

Portage Trail general description: Fairly straight, light grade easy portage with no steep elevation sections. Ground is composed mostly of hard-packed earth and small rock surrounded by grasses. A few boulders on the Longer Lake side closer to the landing. No blowdowns or detours were encountered.

Topographical impediments to traveling: None.

Areas susceptible to impact by periods of rain or beaver flooding: Early spring typical conditions would be high water on landing areas but don’t expect any flooding along the portage itself – no low lying or earthy sections prone to flooding. Some grassy sections may be slick after a rain and earth in spots may turn muddy depending on conditions. Short 5-10 meter section of boardwalks existed closer to Longer Lake where a bit of ground seepage (springs) were observed.
