Fire on Cape Cod: Massachusetts Military Reservation Burns (Part 2)

By far the biggest burns we participated in this past year were a pair carried out on the Massachusetts Military Reservation (MMR). Over two full days the prescribed burns on the MMR covered~330 acres. Both days we had highly active fire behavior, culminating with flame lengths somewhere around 100 feet high and a smoke column that (apparently) was visible from across the bay in Provincetown (35-40 miles). A few days ago I posted pictures from Day 1 of these burns, today is Day 2’s turn.

Again, during the second day our primary job was to hold one of the flanks of the burn. Unlike the first Rx at MMR however, this time we were tasked with keeping our flank burning in lockstep with the far side. Another team was on the true internal ignitions, but we still got plenty of torch time over the course of the day.

The second day’s total hovered somewhere around 230 acres, finishing in a spectacular 100+ foot display that was burning deep inside the unit. We had an easy time on our flank, in part because the vegetation was quite forgiving — A mix of tightly packed dog-hair pitch pines and fuel heavy (but otherwise clear) forest floor. The picture below is a good example of one of the “roughest” areas we were responsible for, the tightly packed pines in the lower portion of the picture acted like ladders, which allowed the flames to reach the upper reaches of their neighbors easily.

There wasn’t much we could realistically do to prevent those trees from torching, instead we mitigated the hazard (of having a tree torch on the perimeter) by having an engine on scene and ready to dowse spots. In large part because of the wind direction that day (note the direction of the flames in the picture below) spotting wasn’t nearly as much of a worry on our flank as it was the first day.

Like the first burn at MMR we participated in, the prescription for this day allowed for full-stand replacement. We kept the pace of the advancing flame front moving slowly in an effort to keep things “cool,” but some torching still occurred. Again, this really wasn’t a concern, just something for us to be aware of all day.

The smoke column generated by those flames went straight up and was apparently visible from as far away as Provincetown.

That just about covers the two MMR burns, unfortunately it was around this time that the camera on my phone decided it had had enough life and quit on me. I’m still hoping (somewhat unrealistically) that I can save the pictures I’d already taken, but I haven’t actually “tried” to extricate them from the apparently broken SD card yet. I’ll figure that out “eventually.” Probably.

Next I’ll be covering our year-end (ish) trip to Baker Island in Acadia National Park.
