#' Snowpack at weather stations in Utah on April 1st, 2011.
#'
#' Water equivalent of snow density (WESD) in mm of water at various
#' location within and surrounding the state of Utah. WESD are
#' measured at weather stations within the Daily Global Historical
#' Climatology Network. April first measurements are used to
#' estimate snowpack for the state of Utah.
