In 1955, some 4,600 acres became available in Marshall's Creek.  Site of a hunting facility, it was found admirably suited for Scouting purposes and purchased jointly by the "Federation" of Philadelphia and Valley Forge Councils.  Joint development and use occurred until 1965, when Valley Forge Council bought out Philadelphia Council's interest and the federation was dissolved.  In 1996 the two councils merged and is now the Cradle of Liberty Council.  Once again the scouts from Delaware, Montgomery, and Philadelphia counties are camping together at Resica Falls.

 According to the original plans, the reservation was to consist of six camps, each holding two hundred and fifty boys.  This would have given the reservation the capacity to handle fifteen hundred campers each week.  Each camp was to have an office, dining hall, pool, staff area, handicraft, ecology and Scoutcraft areas.  These six camps were to be divided with three on each side of Route 402.  Camp #1 was to be situated above the current Firestone Camp; Camp #2 about where Firestone Camp is now; Camp #3 where the family cabins are located, behind Bushkill Lodge.  Camp #4 is now Big Spring Camp; Camp #5 was to be on top of Big Ridge; and Camp #6 was Great Bend.

 Resica Falls opened for summer camp in 1957, and since then has served thousands of Scouts and Scouters.  Big Springs opened as a typical summer camp in 1957 and is still in a full 8 weeks of operation today.  Great Bend opened as a two week summer camp in 1958, but by the late 1960's it was mostly attended by one week troops due to the changing job world that made it difficult for leaders to commit to two weeks. Great Bend was forced to close at the end of the 1980 summer camp season, but some of it is still in use today as a part of Big Springs.  Camp Firestone was opened in 1958 as Firestone Explorer Base, and was used exclusively by Explorers as an outpost camp. The camp staff was very small and the campers were responsible for cooking their own food. Firestone was the birthplace of the Fawn Run program, which utilized guided trail excursions to fully staffed and themed outpost sites that were scattered all over the property. In 1969 Firestone Explorer Base became Camp Firestone and opened for a typical Boy Scout summer camp program with campers cooking their own food.  Lake Roger was opened in 1970 and used for aquatic programs for both Big Springs and Great Bend, with Lake Anne opening the same year for activities at Firestone.  Fawn Run eventually began using Big Springs camp as its home base, around the time of the start of the Boot and Paddle program.  Over time Firestone evolved into a patrol method based summer camp.  The program emphasized the individual scout, patrol, and troop in everything from cooking meals in campsites to campwide activities.  Unfortunately, Firestone Camp was temporarily closed at the completion of the 2004 summer camp season due to lack of participation in the camp and financial restraints.  The future of the camp is undecided, with the hope of rekindling new interest within the near future.

 Resica Falls is still a busy place year round, even with the changes over the years.  Big Springs and Firestone are open for weekend camping during the off season, along with cabins available all over reservation for hunting season.  Resica Falls is also home to 6 miles of the best fly fishing in Pennsylvania, and is stocked several times a year with trout.  The summer camp season is also bustling with activities.  Big Springs is open for a full 8 weeks of Boy Scout camping including the option for troops to cook their own food in their campsites.  Fawn Run runs a reservation wide trek each of 5 weeks offering programs such as Black Powder rifle, Field archery, tomahawk and knife throwing, mountain biking, and more.  Boot and Paddle runs one trek a week for 8 weeks with a 6 mile hike followed by a 72 mile canoe trek down the Delaware River to Treasure Island Scout Reservation.  Several other High Adventure programs are in the works of being created, along with other changes making the future of Resica Falls very promising.
