Dear Sir:
Re: Tower Detection System.
As requested attached is a list of all fire towers in Northern Ontario between latitudes 46 and 51 degrees. Also attached is a small scale map showing the general location of the towers.
For specific tower locations we could in most cases provide area-seen or visibility maps if you would indicate to us the locations for which you would like this information. Generally speaking our towers are located to give a line of visibility of 10 to 15 miles depending on topography.
Yours very truly,
TE Mackey,
Chief, Division of Forest Protection
