The "faceplant" is so named for the nice leafy patterns which the first plantee, a Mr Roger "Big Air" Turnbull, received on his forehead after landing rather forcefully in a gravel patch to the side of the downhill trail section he was riding on at the time (although perhaps "on" is not precisely the right word). This is fortunate, since Mr Air's colleague, a Ms Katherine "Radikal K" Foster landed in the same patch of gravel mere moments later and ended up with an intricate engraving of two dogs, ahem, fighting on her cheek.
