I feel that these images need a little bit of explanation
In 2014 I accompanied my then 10 year old son on his 4th grade trip to Santa Cruz Island off of the Southern California coast. It is the only island in the Channel Island National Park that you can overnight camp at. We hiked about 3 miles with a guide and these are the result from that hike.
