Summary:
Pictured Rocks National Lakeshore in Michigan’s Upper Peninsula experienced dramatic 4-7 foot waves triggered by 15-20 mph autumn winds, creating spectacular spray formations against its iconic sandstone cliffs. MLive photographer Joel Bissell documented these dynamic conditions along the Chapel-Mosquito trail loop, capturing Lake Superior’s signature turquoise waters contrasting with towering sandstone formations like Miners Castle and Chapel Rock. This natural spectacle highlights both the area’s raw beauty and its ongoing coastal erosion processes. The National Park Service reiterated critical safety protocols as Gale Warnings and Small Craft Advisories remained in effect throughout the event.
What This Means for You:
- Visitor Safety Prioritization: Adhere to NPS cliff safety guidelines and check NOAA marine forecasts before coastal hikes
- Photography Opportunity Optimization: Time visits during autumn storm systems for dramatic wave action shots at golden hour
- Coastal Erosion Awareness: Observe but maintain safe distances from cliff edges where subsurface erosion creates instability risks
- Future Outlook: Increased frequency of intense fall storm systems may accelerate cliff recession rates along Lake Superior shorelines

Dynamic Wave Action at Pictured Rocks National Lakeshore
MUNISING, MI – Powerful autumn winds reaching 20 mph generated exceptional 4-7 foot wave heights along Pictured Rocks National Lakeshore’s vulnerable sandstone cliffs this week. Meteorologists recorded extreme offshore conditions with 8-11 foot swells in eastern Lake Superior basins during this coastal weather event.
Renowned landscape photographer Joel Bissell documented the coastal processes while hiking the Chapel Rock coastal zone, capturing turquoise wave refraction patterns unique to Lake Superior’s oligotrophic waters. The National Weather Service maintained Small Craft Advisories and Gale Warnings throughout the atmospheric event.
This coastal erosion episode demonstrates the ongoing geological processes shaping the Cambrian-age sandstone formations. Visitors are reminded to:
- Monitor real-time NOAA marine forecasts
- Maintain 6m distance from cliff edges
- Follow NPS coastal zone safety protocols
Extra Information:
- NOAA Great Lakes Coastal Forecasting System – Real-time wave height and water temperature modeling
- Michigan DNR Shoreline Erosion Monitoring – Annual cliff recession rate data
People Also Ask About:
- When is peak wave season at Pictured Rocks? November gales produce largest swells but October offers better photography conditions.
- How fast are the cliffs eroding? Average recession rates of 15-30cm annually with storm-driven spikes.
- Can you kayak during Small Craft Advisories? Commercial tours cancel during advisories; private kayaking not recommended.
- Where are the safest cliff viewpoints? NPS-maintained platforms at Miners Castle and Chapel Basin.
Expert Opinion:
“These storm events demonstrate Lake Superior’s immense power to reshape coastlines overnight. While spectacular for photography, increased autumnal storm intensity correlates with accelerated erosion rates observed since 2015. Visitors should appreciate but respect these dynamic systems.” – Dr. Elena Torres, Coastal Geomorphologist
