Explore one of Los Alamos’ oldest buildings with real ghost‑hunting gadgets at 1670 Nectar Street from 3-5. Borrow tools like thermal cameras and search for old stories in the dark. Free and open to the public. Cohosted with Los Alamos County Department of Public Utilities.

🌾 The 5th Annual Community Seed Drive is here! 🌱
We’re excited to kick off another season of seed sharing! Starting now through the winter, we’re collecting seed donations to help restock the seed library outlets at Mesa Public Library, White Rock Branch Library, and PEEC.
🌼 How to donate:
Drop off your seeds at either library location in paper bags or envelopes. Be sure to label them with as much information as you can including plant name, variety, harvest year, and any growing notes are especially helpful!
🌿 What we’re accepting:
All seeds are welcome from extra commercial packets you didn’t get to this summer to locally grown and harvested seeds, which are especially appreciated.
