The Las Campanas Infrared Survey

The La; Campanas Infrared Survey is a photometric redshift survey designed to study the evolution and clustering of evolved galaxies over the redshift range 1 < z < 2. The survey is motivated by the construction of a unique, wide-field infrared camera for the Las Campanas 2.5m telescope. The primary goals are to obtain infrared imaging of a square degree to K-s = 21.1 and J = 22.7 along with deep optical imaging in VRIz' We discuss the scientific and technical goals of the survey, and we present the first survey images obtained in April 1999.
