HINES, Ore. -

The Buzzard Complex of range fires in southeast Oregon approached 90,000 acres by late Tuesday, with significant burning activity throughout the day and well into the evening, officials said.

Here's the rest of the Tuesday night update about the fires, which were spreading east from Harney into Malheur counties:

At least two fires merged together in the southern portion of the complex, spreading several miles east toward the Crowley-Riverside Road/Dowell Reservoir area. 

In the northern portion of the complex, more fires merged together and spread south toward Crane-Venator Lane and east toward the sparse community of Riverside.

Difficult terrain, combined with extremely dry fuels and hot and windy conditions gave firefighters a steady challenge.

 Livestock, private property, several ranches, outbuildings, sage grouse habitat and agriculture lands were threatened throughout the day. 

At last report, one barn was lost early Tuesday evening. 

Heavy air tankers, single engine air tankers, helicopters, fire engines, hand crews, bulldozers and other equipment were on scene all day and will work around the clock to protect residences and limit fire spread as much as possible. 

A Type 2 Oregon Incident Management Team 4 (Brian Watts, Incident Commander) has been assigned to manage the Buzzard Complex and assumed operations Tuesday evening.  The firefighter base camp and Incident Command Post is located at the Crane High School. 

Size:  Approaching 90,000 acres (includes all fires with the Buzzard complex)
