Ash Fallout Surprise for Local Residents

Residents in Greater Victoria were taken aback when they discovered their homes and vehicles coated in a fine layer of ash. Initial theories suggested it could be a product of the nearby Mount St. Helens in Washington, but officials from the United States Geological Survey (USGS) quickly clarified that this is not the case.

USGS Weighs In: Ash Origin Revealed

On Tuesday, the USGS reported that although strong winds were stirring up ash from Mount St. Helens—last active in 1980—it is highly improbable that this ash traveled as far as Greater Victoria.

Geologist Holly Weiss-Racine explained that the ash residents are encountering is not volcanic but rather typical of that produced by forest fires.

The Distinct Differences: Volcanic vs. Forest Fire Ash

Weiss-Racine elaborated on how to distinguish between the two types of ash: "If you crush it between your fingers, it should resemble ash from a campfire or fireplace and dissolve in water. Conversely, volcanic ash consists of tiny rock fragments that are abrasive and do not dissolve. Furthermore, ash from Mount St. Helens is light gray and as fine as flour or baby powder."

Wildfire Connection: Bear Gulch Blaze in the Spotlight

The Canada FireSmoke map reveals smoke emanating from the Bear Gulch wildfire, situated west of Seattle in the lush Olympic National Forest. As of September 17, this wildfire has already consumed nearly 4,900 hectares.

Health Advisory: Moderate Risk Levels in Victoria

As a consequence of the air quality situation, British Columbia's Air Quality Health Index indicates a 'moderate' health risk in Victoria and the surrounding West Shore area. The index ranges from one to three (low risk) at the bottom, escalating to critical levels above ten.

For Wednesday morning, the Victoria stations measured at a four, the lower end of the moderate risk zone. Residents are advised to monitor their outdoor activities; while symptoms like throat irritation or coughing arise, it might be best to postpone strenuous outings.
