Answer: The two geographic obstacles that stood in the way of the construction of the Panama Canal was that Panama was very mountainous, and there were a lot of mud slides. One political obstacle was that Panama was part of Colombia. The united states had to negotiate with Colombia before Panama became independent. Engineers had to build a dam, design and build locks, and remove huge amounts of earth and rock in order to overcome the geographical obstacles.
