Cache County in northern Utah's Cache Valley is home to Logan and Utah State University. The county faces earthquake risk from the Wasatch Fault system and flash flooding from Logan Canyon and the Logan River. The narrow Cache Valley geography between the Wellsville and Bear River Mountains creates complex flooding dynamics and can trap wildfire smoke and air pollution creating air quality emergencies. USU's 28000 students create institutional emergency planning requirements.
