When McCracken is lasso'd and pulled through the pool to the other side he (or the stunt double) is soaking wet. However when he is dragged to his feet he is perfectly dry.
The tombstone at the end shows a son of Miguel and Sue died at Gettysburg July 2 1863 but as the action takes place In 1848-1849 this son couldn't be more than 14 years old ( a boy soldier?)
