Daylight in the Canyon is a phrase old-time cowboys used to express how late it was in the morning. Since the bottom of the canyon is the last place to get light on any given morning, this is surely the last possible time to get up and get on with the day. Myron used this phrase to wake his family and/or any hired men he had occasion to call from sleep for the start of the workday. Since Myron was an extraordinarily early riser, there were many people over the years that believed they heard this call from him while it was still the middle of the night. And indeed, it was not uncommon for him to give this call while it was still hours before official sunrise came anywhere to the land.
