The November 2025 edition of Deep Talks will include a chance to hear from researchers working inside the 4850 Level Black Hills State Underground Campus (BHUC), where they work to count the ultra-low levels of radiation emitted from various parts needed to build ultra-sensitive physics experiments at SURF and around the world.

The event will include physicists, located both above and below ground, presenting their work and answering audience questions.
