Almost the exact same thing happened to me pylon. I was turning from 17th Ave. S.W. onto 26th St. because I was sick of riding through the brutal piles of gravel and was hoping 26th Ave. might be a bit better. The back wheel skidded through one of those piles just as I was starting to turn right so I went down hard on my right side. Luckily, my elbow absorbed most of the impact, so my only repair was some new bar tape as it got all shredded in the gravel. There was actually a little piece of gravel embedded in the handle bar itself that I had to dig out of the metal before rewrapping with new tape.
As much as the elbow was a pain in the ass I was pretty happy I didn't trash my new bike either.
