Pumptrack in Biketown, AB

 Thanks for posting this video, looking good! Hopefully you'll have time between digs to answer a few questions

I'm currently building a pump track at the bottom of our garden (goo.gl/fP6SZ) with lots of work gone into site prep and we're now ready to haul dirt and start shaping, but I've been concerned the radius of our berms will be too small to flow well, they're ~1.8-2.0 metres or 70-80 inches.

My questions are:
1. What's the radius of that berm? You seem to handle it pretty well and it looks around the same as what we have to play with, but it could be the camera angle.
2. Approximately how much dirt goes into each berm of that size?
3. The berm looks really fat, can you get away with a skinnier berm if you armour with rock or use heavy clay soil?

Thanks for any advice you can give!

 nice prep work, solid.
1. That berm is 24' Dia 12' Rad
2. That Berm has 24 y3 of mineral soil
3. Yes you can get away with smaller. We make them fat because our parks must endure 'the public'. Between riders with no etiquette and people who never do maintenance we need to beef up our berms so that they last a long time and a rough time.
Your welcome
Can I come ride your track?
Can you send me your timelapse construction shots? I really like how you have documented the build and how it fits in the garden, lovely stuff. I would like to show that to my students at the Cap university Mountain Bike Course.
