One minute knee high flames from the first strike in a damp environment using a knife, quartz, cedar bark, charred cedar bark, drift wood, sticks, dead grass and White birch bark. All items were found after a rainy night on site except the striker knife and small tin used to char the bark. Built a platform with raised back to keep the tinder out of the wet sand. We needed the fire for night catfishing and cooking. The rather large fire ring was already on site. Cedar bark charred earlier during the trip. Platform, char and tinder bundle ready to go. The river was running high 10 feet away, the ground wet so didn't want to put my tinder directly on the cold wet sand. Taking no chances the bundle was also on a medium plate sized White birch bark sheet. Worked out very well. Here is a short video showing the Knife and quartz fire.
