Small acorns, deep history. 🌰

For generations, the Gabrieleño/Tongva and Acjachemen peoples have called this region home. Gathering and preparing acorns for food was an important part of everyday life, nourishing families and communities.

Join us Wednesday, October 14, for an Acorn Harvest at Weir Canyon! Enjoy a 15-minute ride in a safari-style truck with beautiful canyon views before collecting coast live oak acorns for future stewardship needs.

Help us gather these little seeds to support the future of our oak woodlands. Register at https://letsgooutside.org/activities/2026/10/14/acorn-harvest-at-weir-canyon/!

Happy National Public Lands Day! 🌿💚

Today, we’re celebrating the open spaces that give wildlife a home, support healthy ecosystems and give us places to get outside and connect with nature.

We’re grateful for everyone who helps care for the Landmarks, from volunteers and partners to everyone who explores and enjoys these special places.

Here’s to protecting these lands for generations to come. 🌎
