About Us

Every August, amateur astronomers gather at Indian Trail Spring in the Ochoco National Forest, located 45 miles east of Prineville, Oregon, for the Oregon Star party. We go to this remote location for the very dark skies, low humidity, and wonderful nighttime viewing.

In partnership with Ochoco National Forest, Oregon Star Party is a nonprofit organization staffed entirely with volunteers. Operating under a permit issued by the US Forest Service, Oregon Star Party is spread across 40 acres at Indian Trail Spring. This is a primitive site with an elevation of over 5,000 feet and an unobstructed 360 degree horizon. Oregon Star Party is considered to have the darkest skies of any major star party in the continental United States.

Each year, OSP's volunteer planning committee plans youth and adult activities, secures door prizes, and arranges for vendors to sell their wares during the week-long event. Onsite amenities include hot showers, portable toilets, a chuckwagon, wifi, and the ever-popular espresso cart. Volunteers staff the entire event, including a first aid crew.

History of OSP

by Gary Strong

Carolyn and I never liked the distance and weather variability at the Steens. Also the steadiness of the sky was often turbulent, in fact boiling on several solo excursions. (I have been going to the Steens since I was 12 in 1957, the same year I got my 4" Criterion, which did not make the first trip.)

We also loved the Ochocos and had been actively looking for a nice site for ourselves for years in those mountains. The OSP organizers were also dreaming of other sites; we started thinking for a group of 100 or 200 observers.

On May 20th, 1990 we investigated the lower gravel pit and open country on road 4240, just south of Big Summit Prairie road 42. It looked promising, but did not have the south horizon I really wanted. There was a wooded ridge in the way.  We were back next summer camping at this gravel pit and thinking of showing it to Chuck Dethloff, the main person behind the movement to create the Oregon Star Party.

On Sunday morning, June 16, 1991, I was lawn chair hiking with my 10x50 binoculars and spotted a rocky bluff on the ridge about 1 mile away. I wanted to travel through the woods and climb up to it. I love cross country hiking in the Ochocos! The Shoshoni ancestors would surely have had my scalp.

So Carolyn, Tycho and I took off into the tall pines. Of course trees obscured our goal, but I believed I had a good sense of cross country navigating (getting older is screwing it up). But I had no brains to carry a map! We passed a shallow artificial pond created on a spring (Bruner Spring Reservoir). We came upon an overgrown logging road and walked on it for 1/4 mile and then could see the target rocky area. Up we went and found flowers were everywhere, but the best was yet to come.

Far above us and standing above all on the horizon was a tall massive ponderosa. Beyond it was open sky! We starting hiking up a barely visible 4WD trail, probably hunter's tracks. Everything was red soil, rocky, short sage, and grass with sparse flowers. We went through a set of pines, junipers, and mountain mahoganies and could see the big tree was right ahead. Tycho found some elk poop and was rolling in it before we even knew what was happening. Tough shit! Really! And it was foul smelling!

We hiked up to the big Ponderosa thinking it was on the top of the ridge.  What!?  From the tree, it was still over a quarter mile to the next higher horizon!!  We continued up across the large treeless area. It was becoming apparent this might be a great area for observing. I was already thinking of night and the wonderful skies. We made it to the highest point. We were rewarded with a wonderful view to the south and a 360 degree panorama. There was a great road going to the east!! We were tired from the heat and wind and headed back down. A stop was made at the pond to try and wash the tar-like elk poop off Tycho. Then I got out the Ochoco forest map, an older one, printed before the Greenies had the area roads closed or obliterated.

It looked like an easy route to the area. We drove right up 800 road to the site. The road had been prepared for what was going to be a lot of logging up there. We were on top without a tough drive! We looked around and noted the great places to camp, the horizons; the pile of razor wire in the junipers, the neat picturesque dead ponderosa (the future Rob's Tree), the ancient junipers and old mountain mahoganies. The short sage was not a problem...to our simple thinking. I was just imagining the quiet voices of hundreds of astronomers in the future twilights.

I took pictures. I could not wait to tell Chuck; but there were several star parties to go before he could make it.

July passed with a dramatic ridge-edge star party at Larry Mahon's, then for August Carolyn and I visited the Indian Trail site alone, then came September and the OSP at Fish Lake, Steen's Mountain.

Finally there was time for OSP committee members to visit.  It was October 11, 1991. The Columbia Gorge was burning like never before. The heavy smoke traveled south and was joined by red dust and swirling wind. What a great place! It all went away and calm came over the evening. We had 12 observers enjoying the cool fall evening...and by morning Chuck Dethloff was turning the wheels of his Oregon Star Party mind. On December 15th we all met at Chuck's house to decide the next future of The Oregon Star Party and the rest is history.

The big Ponderosa was struck by lightning during the 1993 OSP and is now dead. We found Rob's tree cut down by vandals in 1996 s (read more about Rob's Tree). The site name came from the Indian Trail Spring located just to the southeast of the site. The spring was named for the trail used for countless years by Indians to travel between the Columbia River and the east coast of Mexico. What a beautiful thought we are able to continue enjoying this area as people so long before us did. Shoshoni legend says their people came from the union of an Indian maiden and Coyote (an Indian god, not the prairie wolf) who fell to earth while swinging...from a star.

The Story of Rob's Tree

by Rob Brown.

The tree was discovered by Gary and Carolyn Strong in the Ochoco National Forest in Central Oregon in the summer of 1991. I visited there that October with the OSP committee to conduct a site survey. The site survey was being conducted by the Oregon Star Party planning committee, because a new location was needed for the Oregon Star Party after several years in the too-remote Steens Mountains. I was on the lookout for a landmark that would make a good OSP logo. We had used Kiger Gorge from Steens, and I thought it was a great image. I don't remember everyone who was on the trip, but I do remember Chuck and Judy Dethloff of course, Candace Pratt and her son Garrett, Bruce Johnson, Howard Banich, and Gary and Carolyn Strong.

robs tree #1 I found the site to be a nearly barren hilltop, just red dirt and dammit bushes (sage), lined by tall pines, and this unusual looking dead tree. At first I was dismayed by the lack of stunning visual landmarks, but then after sunset, while the sky was still very bright in the west, I was impressed by the dead tree and took a couple pictures.

When we re-convened at the Strong's house a few weeks later, the committee brought up the subject of needing a new logo for the OSP. I brought out the photo of the tree, which was passed around and soon became known as "Rob's tree picture." robs tree #1 There was very little else in contention, and the photo was chosen because it had high contrast and would easily be transferable to silk-screen for T-shirts and the like. Globular cluster M13 was added by Gary Strong along with the rest of the artwork, and behold, the new logo.

It didn't take long for the committee members to start calling the tree Rob's Tree. Although I took the photo, I never felt comfortable having it named after me, until quite some years later. Now I sure miss it.

The tree proved to be a nice central focal point for the observing site in the first few years. It was the location of the group photograph and the meeting site for evening guided tours of the night sky. Many people saw in it the potential for great astrophotographs, not the least of whom was Mark Seibold, who took the image below, and was awarded "Astrophoto of the Month" by Astronomy Magazine. (He got published twice! September and December, 1994). robs tree #2

My wife-to-be, Julie, went on our first campout together in summer 1994, and visited the site. I had to show her "my tree." robs tree #4

Unfortunately, dead trees do not stand forever. Between 1995 and 1996 the tree was cut down. There are two legends about this, one practical and logical explanation, and one conspiracy theory. The practical story relies on the fact that the tree was right next to the USFS 800 road, and posed a potential hazard. Sure, but 800 is not exactly the Banfield Expressway. The conspiracy theory is rooted in a dispute between an individual who hunts elk in the area every fall and the OSP committee. The theory would have this individual cutting down the tree out of spite. The USFS never claimed cutting it, and they're a fairly up-front bunch of folks so they probably would have fessed up by now. One thing is certain: The tree was cut expertly, it fell exactly 90 degrees to the road, with a very clean, efficient cut.

The following image shows the fallen tree in 2001, much of it has been removed. The image also illustrates the new status of the landmark! robs tree #1

In 1996 Julie and I wrote and performed " the Grinch Who Stole the OSP" just prior to the door prize drawing at the OSP. Perhaps this fueled the conspiracy theory, but it was silly and enjoyed by all.

Epilogue:

The second annual OSP, in 1993, made us all wonder why we left the Steens and the unpredictable extreme weather. We had increasing clouds on Weds night, and by Thursday morning it was starting to rain. Things rapidly deteriorated, and by about noon we were experiencing a severe thunderstorm with hail. The electrical storm increased through the day and into the evening. By 4pm I was afraid for my life as I huddled in a car with Rich Poletti, Candace Pratt, and Carol Cole (Huston). The telescope field was being hit! Direct ground strikes were happening all around us at a rate of several per minute, and the thunder never stopped.

There was a brief break before nightfall, then it started again in earnest. I put my life in the hands of God, and retreated to my tent, which was located irresponsibly close to the trees. (IN the trees, actually, but I wasn't the only fool.) The bombs kept exploding for hours. Sometime after midnight I think, one particularly powerful one struck, on the North edge of the site. The next morning, we slogged through the mud to discover a very large ponderosa with a gaping spiral scar running its full length, the bark freshly peeled, and a small crater in the earth at the base. Bits of bark were strewn for quite some distance from the tree. Over the years the life has drained from the tree, producing yet another dead tree landmark:

Soon after the blast people were calling it Chuck's Tree, in (dis)honor of the OSP founder and chief organizer Chuck Dethloff. (Mainly as a way to vent their frustration and blame Chuck for the weather!) The spiral scar is still easy to see. Eventually the small branches will fall away and it will start to resemble Rob's Tree. It is the largest dead tree at the site, far larger than Rob's Tree before it fell.

Amazingly, we observed the night following the storm, and two nights later, Saturday, we were rewarded with possibly the best night of transparency and steadiness ever seen at an OSP. (There are other contenders...but none are as memorable to me, especially in contrast to the previous events that weekend.) I was personally rewarded with the grand prize of the OSP drawing that afternoon: A 12.5" scope built and donated by Chuck himself!

I can't think of a better symbol of the Indian Trail Spring observing site, except for maybe the clear, steady, and dark skies that make it one of the top-notch locations in the US for amateur observing.

OSP Group Photographer Bruce Johnson tells this story:

"I had located my tent in a picturesque grove on the far NE side of the site, just 120 yards from Chuck's Tree. I was crouched awake on a pile of electrically-insulating things to protect me from possible ground currents, but a greater danger occurred when the Tree was hit, and the thunder boom and blinding light instantly followed by a tremendous crash and the sounds of heavy objects crashing through the trees to the ground. In the morning, a survey revealed the cause of at least one crash, that being a stout spear-like tree splinter about 2 feet long, impaled in the ground not 50 feet from my tent.

The following year, my father, a retired forester, visited the site and heard the story of the tree. At that time, the tree's needles were still largely green, and popular talk was 'Wow, what a powerful totem tree we have here, it took a strike like that and is going to pull through.' Well, my father, in his years of experience, said, 'Not gonna be, it'll take a few years, but it's a goner.' And he was right. Year by year the green left, and in another decade of the [long] life of trees, it'll be a skeleton."
