Just after 2:30 pm units from Salisbury Mills and Washingtonville E-580 were alerted for "smoke coming from a house" in the Mountain Lodge Park community. As units were responding PD arrived and reported a working house fire. SMFD car 1 arrived and advised of a 1 story 20x30 residence with fire showing and requested the 2nd alarm. The house was situated at the end of one of the trail like roads in Mountain Lodge making access difficult. In coming units utilized 2 separate trails to get to the fire building. E-580 arrived as the second due engine and stretched a line to side 4 of the well involved house. TA-577 responded on the second alarm and supplied SMFD E-546 (first due engine). Units remained on scene for just under 1.5 hours before returning to Washingtonville.
