Heritage Day 2015
Join us at Marsh Creek State Historic Park for the second annual Heritage Day from 10 a.m. to 4 p.m. on Saturday, October 17th, 2015.  Participants will have the opportunity to walk right up to the building and look at some of the 7,000 square feet of space inside.  While the interior of the home is not safe to enter due to stabilization work, the six foot tall lower level windows will be opened and provide a good view of the interior. The Brentwood Concert Band will perform period pieces like those performed in the late 19th and early/mid -20th Centuries.  A guided hike will allow visitors to explore parts of the park that are currently inaccessible to the public.  There will also be presentations on the former Native American inhabitants of the area, the pre-statehood Californio period and the Westward Movement triggered by Marsh's letters back east encouraging settlers to come to California years before gold was discovered.  Activities for children include excavating "artifacts" from midden boxes located near the site of 7,000 year old archaeology discovered near the house.

The event is free to all participants- donations to help support the John Marsh Trust are accepted.  Root beer floats and hot dogs will be available for purchase.

Project/Site Description
Cowell Ranch/John Marsh encompasses 3,659 acres of natural habitat, wildlife, and unique cultural features, including the historic John Marsh Home.  John Marsh lived on the property from 1837 to 1856. He was the first American Citizen to settle in what today is Contra Costa County.  He was a medical doctor and developed Rancho Los Meganos as a large cattle ranch.  The John Marsh Home when completed in 1856 was considered the "finest ranch home in California".  Through the efforts of concerned citizens as well as the Trust for Public Land and other entities, Cowell Ranch/John Marsh is one of California's newest state parks, although currently not open to the public. 

Partners in Park Planning
In a collaborative partnership, California State Parks and the City of Brentwood Parks and Recreation Department are participating in a joint planning process to plan the future development of Cowell Ranch/John Marsh.  Working together with the community, this planning process will create a vision for the future; provide recommendations for the future of the historic John Marsh House, public recreation access, and natural resource management as well as guidelines for implementation of a long term vision for the Park so it can be enjoyed for years to come.
