Water Damage to the Awaba DH Trail.
This is a photo taken today of sediment runoff from Mt Faulk road onto the berm below the scorpion gap at Awaba. The road was freshly graded not long ago.
the sediment in here would be up to 500mm deep in the middle of the berm.
A lot of work had been done here in the past to make sure water coming from the road above doesn;t erode the trail, but we have never had a sediment deposit situation before.
Erosion everywhere
In case you haven't noticed, we're a bit passionate about trail advocacy around here. I mean, without trails to ride on, where would MTB be?
Anyhow, another thing you might have noticed is that opponents of MTB have a standard list of complaints about cyclists - most of them unfounded. One of their favorites is their claim that mountain bike riders cause erosion.
What really causes erosion?
The attached pictures were take on Sunday 8 August 2010 and emailed to me couple of days ago. They were taken by a walker, walking round the walking track at Manly Dam.
Manly Dam is one of the few places in the area with legal single track and as you would expect, this means that there is no evidence of riders being tempted to go elsewhere (when legal riding is supplied there is no reason to ride illegally). IE. there is no evidence of any riding on these tracks from the pictures.
