ExplorationWorks 19th Annual Nightmare Affair

Join us for a spooktacular evening at the 19th Annual Nightmare Affair Gala on October 24, 2026, at the Great Northern Best Western Hotel from 6:00–9:00 pm. After dinner, stick around for music and dancing until 11:00 pm. This adults-only Halloween celebration promises a night of thrills and chills—all in support of science education. Enjoy a delectable dinner, sip on science-themed cocktails, enjoy a science show, participate in our costume contest, and bid on an exciting lineup of items during our silent and live auctions. With live music by Ten Years Gone, the energy will stay high as we come together for an unforgettable night of fun and fundraising. Can’t make it in person? You can still be part of the Nightmare Affair by joining our online auction, October 18–24, featuring a wide variety of unique packages. Your support at this event helps us continue inspiring the next generation of scientists, innovators, and leaders in Helena and beyond.
