Unearthing the Past: How LiDAR Reveals Hidden Histories Under Our Feet

The advent of LiDAR (Light Detection and Ranging) technology has revolutionized the way we explore our surroundings, peeling back layers of time to reveal secrets buried beneath the foliage. This laser-driven technique, originally designed for geological studies, is now uncovering fascinating chapters of human history, including the remnants of a forgotten lake in Kirkland, Washington.

The Discovery Journey

Local historian Matt McCauley has been diving deep into LiDAR databases, merging modern technology with traditional historical research. His passion for history has led him to discover remnants of a vanished landscape, including the mysterious Juanita Bridge and the ghostly traces of a wooden causeway.

• Juanita Bridge: Once a vital crossing, now a pedestrian-friendly path.
• Wooden Causeway: Built in the 1890s, this structure once spanned open water.
• Phantom Lake: Known as Lake Juanita, it was created by early settler Dorr Forbes.

LiDAR: The Game-Changer

According to McCauley, LiDAR offers a unique perspective: "It digitally strips away the foliage, allowing us to see the contours of the land and any hidden structures that may have been forgotten." This innovative approach enables historians to confirm locations that were once mere speculation.

Revealing Forgotten Structures

Through LiDAR imagery, McCauley confirmed the location of the causeway that had long been obscured by time and vegetation. "I was pleasantly surprised to discover that the ghostly remnants of that causeway are still visible," he noted, emphasizing the importance of this technology in historical research.

Hidden Histories Beneath Our Feet

Not only does LiDAR reveal structures like the causeway, but it also uncovers entire landscapes that have faded from memory. For instance, evidence of Lake Juanita, which existed from the 1880s to the early 1900s, is now being rediscovered thanks to LiDAR's precision.

Exploring New Frontiers

McCauley is not stopping at Lake Juanita. His exploration extends to other areas around Lake Washington, where he aims to unearth more hidden pieces of history. "We have another project down in Newcastle involving the old Seattle Coal and Transportation Company tramline," he mentioned, hinting at the potential discoveries that await.

Conclusion

LiDAR technology is not just a tool for scientists; it is a gateway to understanding our past. As historians like Matt McCauley continue to utilize this innovative technology, we are reminded that even in our modern world, the echoes of history lie just beneath the surface, waiting to be discovered.
