Opening the chest at Marie Yazzies:
Return to the house where Shorty was found. Now look at the clock above the fireplace. It will tell you which numbers to use to open the chest. Think of it as a clock, and look closely.

In order to open the trunk at Mary Yazzie's, go to her store and look at the books entitled "Like Wind Through My Heart" by Cheerlena Purceel. Obtain her phone number and call her from where your at. She will tell you the day, month and year the people with the initials E.H. and A.H. were married. To open the trunk you need to have the screw things from the rolltop desk at the ranch. Now put them in and turn them all facing up. Turn the first one the number of the day of the marriage, turn the second one the number of the month, and turn the third one the number of the year. The trunk should open.
