Give to Camp
We are inspired by what Leslie Marrowbone envisioned 50 years ago on the shores of Lake Oahe. 1971 is when the Sioux YMCA made its stance to youth development with our first ever summer camp. The years have been unique, not without challenges, but with huge reward.
Thank you to all of our supporters who made the growth of camp possible. We are aiming to raise $50,000 for our campers. Here is a breakdown of what your gift can do for our youth:
​
$20 - Provides S.T.E.M. and craft supplies to enhance our intentional camp curriculum
$50 - Provides essentials, including sleeping bags, bedding, and toiletries
$100 - Provides 25 healthy and nutritious meals and snacks
$250 - Provides one week of transportation for campers to eliminate barriers
$500 - Scholarships a camper for an amazing week at Camp Marrowbone
$1000 - Scholarships a 2 week Teen Development Participant, includes college visits
