The SnowPAC Conference Series was initiated in 2009 as a way to bring together researchers in Astronomy, Particle Astrophysics, and Cosmology to share common research interests and Ideas. SnowPAC 2009 was the inaugural conference of the yearly SnowPAC conference series. The seven day conference included sixty-one participants and fifty plenary talks.

The Scientific program SnowPAC 2009 was focused on four main topics: (1) High Energy Cosmic-Ray and Gamma-Ray Observations; (2) Neutrinos; (3) Dark Matter; and (4) Particle Cosmology and Gravity. These conference proceedings present highlights of the talks from the first SnowPAC conference.

This book is of interest to researchers in Particle Astrophysics, Astronomy, and Cosmology. It presents a review of current topics in these fields, as well as recent progress and discoveries.
