In preparation for my canoe-O this Saturday in Newton, I took the commuter rail out to Brandeis and walked to Charles River Canoe and Kayak. I have a season pass for CRCK, so the trip cost about $8 for transportation and map printing. I was unable to record the excursion via GPS because my garmin battery was low.
I explored the northern part of the Auburndale Canoe-O map. The land forms are good, but the water vegetation are outdated or entirely unmapped. I found that there are at two major types of floating vegetation in the area- the
broad, large lily pads and what I assume is the
Water chestnut, trapa natans. The lily pads are basically impassable, since they have heavy stalks that snag on the bow of a boat. The water chestnuts were passable in places of low density, but a significant fight as they thickened. I found a good indication of passability was the height of the water chestnut leaves above the water; if they had any relief at all (> 3 cm), they were impassable. I spent at least thirty minutes testing the feasibility of traversing several areas; in one case, I spent a few minutes advancing about thirty centimeters with each laborious stroke. Getting stuck in the water chestnuts reminded me of Frobisher, trapped in the ice, and the water was too deep to get out and push. I think I'm a fairly strong kayaker, so I'm unlikely to use the lilies substantially on the course. Each time I forced my way through sections of lilies, I left a conspicuous trail through the matted green. I suspect I did enough damage to the vegetation that it would be easier to follow the same track rather than to force one anew.
After I returned the kayak, I walked about 25 minutes to the Brandeis commuter rail stop, discovered I had misread the website and the next train was due in two hours, and backtracked 35 minutes to the Riverside T stop. This was my longest excursion without crutches in the past few weeks.
