Funny name for a waterfall but? In 2013 Lawn lake that was up in the mountains failed and 29 million gallons of water came rumbling down the mountain side taking everything with it. What was left was a 42 acre alluvial fan. The tops of...More

I have studied this disaster for years in geology and natural hazards classes. Truly amazing and unable to imagine the force of the water and extent of distruction unless you go and see the size and quantity of boulders. The fall is beautiful and massive!

Get out and explore Alluvial Fan. In addition to an interesting place, it is also a great place for photo taking.

Climbing the stones and boulders left behind by the glacier is a very unique experience unlike the regular hiking. Lots of fun for kids and adults. Get to soak your feet in the refreshing water cascading down.

Questions & AnswersAsk a question
Hi all, I am planning to go the Alluvian Fan next week during our visit to RMNP. I am planning to reach there late afternoon, around 5 pm with a 3 yrs old. Is it a good time to go there? Also, from the park map I think it is not a one way drive for Old River Fall Road but when I ask the direction I google map for way back to Estes Park it is asking me to drive all the way Old River Fall Road then returning by Trail Ridge/34/36. Also, the ORFR is not opened yet I think. Please let me know if I can return to Estes Park. Thanks.

Is the map on tripadvisor accurate as to where the Alluvial fan is located? It seems like after researching the Alluvial fan is located in a completely different place.

If you enter the Fall River Entrance to RMNP, the Alluvial Fan is about 3 miles from this entrance. You will see the right hand turn off highway 34 onto Endovalley Road. There is a sign. You can download the official RMNP... More
Can I return to EstesPark from Alluvial Fan parking lot directly or I need to complete the old Fall River Road following the Trail Ridge Road?
