Join the Caltech Y Outdoors on a long-weekend camping and stargazing trip to the Mojave National Preserve! Enjoy stargazing at night, away from city lights, and by day, exploring a desert environment with sand dunes, Joshua trees, petroglyphs, and lava tubes.

Come prepared with sturdy hiking footwear, plenty of warm clothing and layers (it gets cold at night!), at least 3L of water bottle capacity for hiking, sun protection, and a mess kit (or a container and utensils). The $20 cost covers camping equipment, including tents, sleeping bags, and sleeping pads, if needed, and camping meals (including vegetarian and vegan options). Please inform the Y and trip leaders of any allergies.

Transportation is not provided, but we will help organize carpools before the trip. Please be prepared to chip in ~$30-40 to the drivers for round-trip gas costs, in addition to the $20 trip fee.

Students are given priority and spaces are limited, so be sure to complete and submit all signup forms as soon as possible. Once spaces fill up, all subsequent signups will be placed on a waitlist. We will inform folks on the waitlist if spaces become available. Please reach out to Y Outdoors leaders Ria (riar@caltech.edu), Rithvik (rramesh@caltech.edu), Satvik (sgkumar@caltech.edu), or Tim (timproudkii@caltech.edu) if you have any questions.

Join the Caltech Y for a thoughtful conversation with Rev. Dr. David Wilkinson exploring the intersection of faith and science. For many individuals, faith is a core part of who they are, informing their values, sense of purpose, ethical frameworks, and understanding of humanity’s place in the universe. Dr. Wilkinson brings a unique perspective as both a theoretical astrophysicist and a theologian. This event invites participants to reflect on how scientific inquiry and religious belief can coexist and contribute to a fuller understanding of the human experience.

Sign-up is required.
