Golden’s Magic Mountain Open Space is 5.5 acres located between Fire Station No. 24 on Heritage Road and the paved Kinney Run Trail. Suburban houses align the northside and Apex Gulch on the southside. The name refers to the former Magic Mountain amusement theme park that owned the land in 1959-1960 when two Harvard archeologists conducted their archeological digs on the site. The site became well known and scientifically important.
As noted on the Denver Museum of Nature and Science website, “Magic Mountain Community Archeology”:
“The Magic Mountain site in Golden, Colorado, has served as a cross-roads of culture for millennia. From the mobile hunter-gathers who lived there for over 9,000 years to the gold-seekers of the 1860’s, to those who bike and hike in the area today, there is a collective awareness that the place is special.” (1)
In 1980, the Magic Mountain archeological site became listed on the National Registry of Historical Places as noted on the National Park Service website. At this time the property was privately owned.
In 2020, Magic Mountain Archeological Site received the Stephen H. Hart Award for Historic Preservations based on the archeological digs in 2017 and 2018. (2)

As an environmentally sensitive area, public access is prohibited on the actual site, however, the paved Kinney Run Trail passes by the site. Parking and restroom amenities at the Apex Park trailhead are nearby.
Magic Mountain open space is sloped terrain created by the erosion of soils and clays from the foothills above the property. The site does include a unique outcropping. Grasses and flowering plants help to reduce erosion, especially in times of heavy summer rains hitting the foothills.
Written plant inventories of this area include more acreage than that of the 5. 5 acres of the Magic Mountain Open Space site. Thus any list of plants needs to be reviewed in light of what is actually growing on this open space site.
In general terms, the site is part of the “Foothills Shrub and mixed grass prairie”. A more specific list of plants is provided by Tom Schweich on his website.

Local reports note the presence of coyotes, elk, deer, bobcat, white tail rabbits, meadow voles, rattle snakes, bull snakes, skunks and raccoons plus a variety of bird species.
On a daily basis this open space forms a scenic backdrop for residents of Heritage Dells. Users of Kinney Run Trail also enjoy the view of the Lyons Limestone rock outcropping that serves as a forefront to the views of the Hogback and distant views towards Denver and the urban plains.
The large rock outcropping of tan Lyons Sandstone at the western end was formed by deposits of ancient rivers. This geological formation is found throughout Golden. Farther north, between Boulder and the city of Lyons, this tan sandstone formation was deposited as ancient sand dunes that produced the attractive flagstone sold today for landscaping and patios.
As viewed from the Kinney Run Trail are the cross-bedded layers stacked one above the other that show how the Lyons Sandstone outcropping was formed.
The archeological dig sites are located in long-ago fast moving stream deposits beginning about 11,000 years ago since the end of the last ice age. (3)
Prior to professional archeological digs, the area was known as Apex, or the Apex Gulch site after the historic town of Apex. For many years people searched and looted this and other sites for Native American arrow heads, beads, and other artifacts. In 1959 and 1960, two archeologists from Harvard University set up digs near the Lyons Sandstone rock outcrop on the north side of Apex Gulch. At that time the land was owned by the company that was building the Magic Mountain theme amusement park. The archeologists, in acknowledgement to the company, called the site “Magic Mountain”. (4) The digs in 1994 and 1996 were on the south side of Apex Gulch on city land plus a dig on the privately owned land with approval by owners near the Lyons Sandstone rock outcrop.
In 2000, the city purchased the 5.5 acres on the north side of Apex Gulch and recent digs in 2017 and 2018 occurred on the expanded area now called “Magic Mountain Open Space”. For non-archeologists, the area south of Apex Gulch has reverted back to its historical name and it is now part of the relatively new Apex Open Space Trailhead.
The 2017 and 2018 digs were done by the Paleocultural Research Group, a non-profit organization in conjunction with staff from the Denver Museum of Nature and Science. (5)
The new digs incorporated modern technology. In preparation for the dig. In 2016 archeologists used a magnetometer to go across part of the acreage. The researchers identified 61, one-meter dig sites. The purpose of the new digs was to investigate the Early Ceramic Period (200 -1000 CE) to include “mobility patterns, seasonal use, and site activities”.
Researchers found over 500 stone tools including 72 corner-notched arrow points or arrow point fragments. Only eight pottery sherds were recovered, all likely from the Early Ceramic Period. (6)
Given the amount of “small cutting tools, ground stone tools, cores and arrow points” … “All of this, combined with the lack of visible architectural features (with one possible exception), indicate that the Early Ceramic occupations at Magic Mountain were primarily task-focused rather than seasonally residential”. (7)
The people were using particular raw stones from South Park and Southern Front Range which indicates places they were traveling. Magic Mountain was a place they lived for some part of the year shaping stones into arrow points and other tools which were used to hunt deer and small mammals.
The other important feature of the archeological project in 2017 and 2018 was the incorporation of citizen science into the project. This included use of youth interns working at the dig site, public engagement through guided tours, hands-on opportunities for family members to experience actual fieldwork, public presentations and regular online updates.

The site also contains photographs of the digs and prior history. From archeologists’ views, the early digs south of Apex Gulch and the recent digs on north side are part of the same Magic Mountain Site.
