Where to find Pahoehoe Lava
Hawaiian Islands, USA
Extensive pahoehoe flows are found on all active volcanoes, particularly Kilauea and Mauna Loa, showcasing classic ropy textures and lava tubes.
Iceland
Numerous volcanic systems produce pahoehoe flows, especially in rift zones and shield volcanoes.
Galapagos Islands, Ecuador
Active shield volcanoes exhibit widespread pahoehoe flows.
Canary Islands, Spain
Volcanic islands like La Palma and Tenerife feature significant pahoehoe formations.
Columbia River Basalt Group, USA
Ancient, extensive flood basalt province with preserved pahoehoe features, though often weathered.
Collecting tips
- Look for Ropy Textures. The most distinctive feature is the smooth, undulating, or rope-like surface. This texture is unique to pahoehoe.
- Observe Flow Morphology. Pahoehoe flows often form broad, relatively flat sheets or lobes, and can create lava tubes. Look for these larger-scale features.
- Check for Vesicles. While not exclusive to pahoehoe, the presence of gas bubbles (vesicles) is common in basaltic lavas and can help confirm its volcanic origin.
- Consider the Geological Context. Pahoehoe is found in areas of active or geologically recent basaltic volcanism. Knowing the regional geology can guide your search.
- Safety First. When exploring volcanic areas, be aware of unstable ground, sharp lava, and potential for active volcanic hazards. Wear sturdy footwear and protective clothing.
Quick Check
- Color:
- Dark gray to black
- Luster:
- Dull to vitreous
- Streak:
- Gray to grayish-black (difficult to obtain due to hardness)
