NGC 3310 is a local (d = 14 Mpc) starburst galaxy that shows signs of a recent and complex merging history. Its most well-known debris features are the "bow and arrow" which extend to the northwest and are strong sources of H-alpha emission. NGC 3310 is also surrounded by a radially symmetric network of shell-like stellar debris, and a large closed stellar loop emanates from the eastern side of the galaxy and rejoins in the north. It has an H I disk and two massive H I tails. One tail begins in the northwest and coincides with the bow and arrow, and the other extends to the south. We present deep UBV and R photometry of this debris network and a compare these results to spectral synthesis models used to examine the origins of these debris. We find that the shell-like debris are not consistent with having originated in NGC 3310's disk and that the underlying disk in this system is extremely blue. We also examine the surface brightness profiles of this system and will discuss the implications of our results for the merging history of NGC 3310.
