National Clean Up Day – Leave No Trace Event sponsored by Thomas’® English Muffins

For the second consecutive year, Friends of Lake Sammamish Park is thrilled to partner with Thomas’® Breads – makers of the iconic Thomas’ English Muffins known for their signature “Nooks & Crannies” texture – to make an impact and give back to the local community on National Clean Up Day (Saturday, September 17th) with a morning session (9am – 12pm) and an afternoon session (1pm – 3pm).

An active supporter of environmental sustainability, Thomas’ is seeking 100 volunteers to help clean up the park, maintain trails and do habitat restoration. Thomas’, the National Clean Up Day Sponsor, will help support and facilitate the volunteer service event. Help Thomas’ and Lake Sammamish give some love to the adventures of this special place and to the trails that have sustained the community and nature enthusiasts.

The continued partnership with Thomas’ represents a commitment to restore and improve public lands throughout the Pacific Northwest. Focused on protecting Lake Sammamish State Park’s ecological health, the collaboration will support ongoing restoration efforts and enhance opportunities for outdoor recreation today as well as for future generations.

During this event, volunteers will be given the option to help with trail maintenance, trash pick-up, weeding, blackberry removal and park beautifications. 

All volunteers who participate will be invited to gather after the morning session and before the afternoon session event from (12pm – 1pm) at the Creek Shelter for a complimentary meal to remember featuring Thomas’ favorites like English Muffins and Bagels.

Participants will also receive a branded t-shirt commemorating the effort.

  Sign up now to save your spot!

** Please read the Photo Release and Liability Waiver documents and bring along the signed copy when you check in to volunteer.
