Chamizal National Monument Walk – June 2021 We took the dogs for a short walk at the Chamizal National Memorial on the border of Texas and Mexico. Nice day for a Sunday morning stroll in the park. The monument building at Chamizal Chamizal is more than just an urban park to recreate or enjoy a quiet afternoon. These grounds are a reminder of the harmonious settlement of a 100-year boundary dispute between the United States and Mexico.
