		<description>Turns out to be a surprise for many who get a letter that a fracking rig will be showing up soon on their farm, ranch, or suburban neighborhood. The drilling companies have to pay for surface access, but it is a small amount.

If you look at the GIS maps provided by counties, sometimes you can see a small area within the parcel that is excluded from the deed.

We were looking at a property a few years ago. Lovely place. But when I checked into the mineral rights, the seller was severing them from the surface rights. And researching mineral rights is not easy. Colorado has a very good website showing all the oil and gas fields, the permits, active, old, and pending. It also shows where the fracking holes are. It would blow your mind.</description>

		<description>but if someone else owns the mineral rights they can come onto your land and destroy it to get at what lays below it...

Its a sick system catering to those with money and no morals.</description>

		<description>Initial media reports seemed pretty set on the possibility that members of the religious group in the area somehow started it?

You think they might be innocent?</description>

&lt;blockquote&gt;The Marshall mine fire site is located approximately 1 mile south of Boulder, CO on the southeast corner of the intersection of Hwy 93 and Marshall Road. The mine
fire is located on City of Boulder Open Space.
In October 2003, it was reported that the fire was moderately active with ground
temperatures ranging from 118°F to 130°F. The smell of coal combustion was noted
near the venting fractures (Renner, 2005).
In February 2005, a recently constructed building was inspected for damage
caused by subsidence believed to be related to the Marshall Coal Mine. Vents and
subsidence features were identified under and around the building (Amundson,
2005).
On December 20, 2005, a brush fire was started by a hot vent from the Marshall Coal Mine Fire. The fire was quickly
contained and extinguished. The origin of the fire was traced back to a 373°F vent. In January 2006, fire abatement
was undertaken by the Office of Surface Mining to fill in vents with small rock material to reduce the potential of
starting another surface fire. 275 tons of unwashed aggregate was placed over the vent area to a total depth of
18 inches (Blackburn, 2006).
In 2016, two areas of trough subsidence were excavated, compacted, and backfilled to natural grade. Both areas,
shown on Figure 4-4, were in areas where surface expression of the mine fire had been observed. During the
subsidence mitigation work, a few small vents were uncovered in both locations. In all cases, the exhaust was
warm, moist air with temperature less than 90°F. No new evidence of subsidence or other indicators of the coal
mine fire were observed during the completion of the remedial activities. Gas monitoring during construction did
not detect gases associated with coal combustion over the background levels.

FIRE OBSERVATIONS
The fire was visited October 2018 after one inch of snow fell the previous night. The fire area was inspected, and
no signs of fire features or snowmelt were observed. Additionally, no coal combustion odors were noted during the
site visit. The area was not imaged with a UAS due to City of Boulder Open Space restrictions. Drone perspective
photographs were collected from outside the property boundary.
FIRE RISK AND RECOMMENDATIONS
The fire’s activity is very low and thus presents little potential to start a surface fire. Although the fire is on City of
Boulder Open Space and near the Marshall Mesa parking lot, the off-trail fire area sees little foot traffic, and there
are no dangerous surface features. The fire poses limited risk to public safety.
No abatement is recommended. This fire has behaved erratically in the past, so it is recommended that it be
monitored annually to check for increases in fire activity.
