About the event

Cal-Earth in Hesperia had a highly popular field trip program. However,  due to the pandemic, they had to discontinue the program. But  now...HFAdventureCommunity has the honor to be invited for a special  program to possibly get their field trips program started back up again!  We couldn't be more grateful for this opportunity and hope your student will join us.

Are you ready for an amazing day of learning at  Cal-Earth in Hesperia? Get ready to dive into the world of architecture,  humanitarian aid, sustainability, working with nature, biomimicry, the  strength of the arch, and even the ancient Persian poet, Rumi! We'll  start with a guided tour and discussion to get our brains going, then  move on to some hands-on fun. You'll get to learn all about brick arch  building, explore the domes, and get your hands dirty with some Superadobe bag laying instruction, and mud plaster application to really put your skills to the test. 

We are looking forward to learning new skills alongside friends, and discovering how architecture can be a powerful tool for humanitarian aid and disaster relief. Together, we'll gain a deeper understanding of how to work with  the natural environment, embrace sustainability, and ultimately become  more empathetic and responsible global citizens.

Date: Saturday May 20th 

Time: Approximately 9am-3:30pm (time may be adjusted slightly)

Age: Grades 3rd-12th, divided into age groups where necessary for optimal learning

Can parents attend? YES!!! Parents are welcome to stay at no additional cost! All students must have a ticket.


Here is a little more information about the super adobe!

What is Super Adobe?

SuperAdobe is a form of earth bag architecture developed by architect  and CalEarth founder Nader Khalili. Using long sandbags ("SuperAdobe  Bags"), barbed wire, on-site earth and a few tools, Khalili devised a  revolutionary building system that integrates traditional earth  architecture with contemporary global safety requirements, and passes  severe earthquake code tests in California.

This technology has  been published by NASA, endorsed by the United Nations, featured in  countless world media outlets, and awarded the prestigious Aga Khan  Award for Architecture in 2004. It comes from years of meditation,  hands-on research and development. Inspired by traditional earth  architecture in the deserts of Iran and adapted for modern usage.  Simplified so that anyone can build.

Cal-Earth believes that the whole family should be able to build  together, men and women, from grandma to the youngest child. We have  spent many years researching how to make the process simpler and easier.  There should be no heavy lifting or backaches, no expensive equipment,  and a flexible and fast construction. The bags are filled in place on  the wall using small pots like coffee cans, or even kitchen utensils.  You can build alone or as a group.
