The problem with the explosives used during the carving of Mount Rushmore was primarily related to safety and precision. The original blasting methods resulted in the removal of too much rock, making it difficult to achieve the desired detail and likeness of the presidential figures. Additionally, the use of dynamite posed risks to the workers and the surrounding environment, prompting a shift to more controlled techniques for the finishing touches. Ultimately, this led to a more careful approach in sculpting, emphasizing artistry over brute force.
