So who is to say a land swap will involve the Breaks, or an access road and land and when?
Since the Anchor Ranch in the Breaks is what has been proposed by the group wanting the exchange, I think that answers the "who is" question. It is the owners of said ranches who have approached the BLM to consider an exchange, not the BLM approaching the ranch owners
I think the official proposal from the Wilkes Brothers will be soon forthcoming. Hopefully that will give us certainty of what has been proposed.
Where are the rumors coming from?
The emails I have are coming from BLM people authorized to lead the BLM on such discussions. I suspect that is where the information is coming from.
To note, the BLM has stated they do not want to go another hunting season without access to the 53,000 acres in the Bullwhacker area that is no longer accessible through the Anchor Ranch. The BLM has stated that if the exchange is not supported, they want to find other alternatives to access the Bullwhacker parcels.
Point being, we can get much better deal than what the has been tentatively proposed. Maybe the official proposal will be more appealing.
Given the BLM is interested in keeping access at, or above current levels, and there are many people/groups talking about this, publicly and privately, we might be able to keep all parcels and have access to all of them.
