Historical Information

With the extension of the Lake Superior and Mississippi Railroad into Duluth in the late 1860's, the harbor quickly assumed the role of the major shipping point for the bounty of America's bread basket to the west. Wharves, harbors, piers and elevators sprang up around the growing harbor to handle the incoming train loads or grain to be loaded on awaiting vessels for shipment through the Soo Locks to the hungry cities of the lower lakes.  Standing directly in the straight-line path between Duluth and the northern tip of the Keweenaw, the Apostle Islands represented a significant threat to mariners navigating across Superior. With Outer Island the most northeasterly of the group, the island quickly assumed an important role as the turning point for both up and downbound vessels. However, with Outer Island Shoal lying a mile and a half to the north of the island, captains had to take care to give the island sufficient berth, or chance ripping their hulls on the rocky bottom lurking a mere ten feet beneath the surface.

Taking up the cause of maritime interests on April 4, 1869, acting Senate President Pro Tempore Benjamin Franklin Wade of Ohio presented a memorial on behalf of the Wisconsin State Legislature praying for an appropriation for the construction of lighthouses to mark Outer Island. The matter was referred to the Committee on Commerce for further investigation, and while the Lighthouse Board repeated the plea for the station's construction in its 1871 and 1872 annual reports, no movement was forthcoming until March 3, 1871, when an appropriation of $40,000 was finally made for the station's construction.

Responsibility for the design of station buildings was that of Eleventh District Engineer, Brevet Brigadier General Orlando M. Poe. Prior to this point, the designs for Eleventh District Lights had been largely utilitarian, of basic "shoe box" design with little ornamentation or thought as to the quality of life for the station's keepers. Poe's design for the Outer Island Light was unique, in that it was designed not only to be thoroughly appropriate for the need, but also included design elements normally reserved for major public buildings and stately homes. Poe's plans for the station called for a cut stone foundation supporting an 80-foot brick tower gracefully tapering from its base to the gallery, which was supported by a series of 16 ornate corbels. Immediately below the gallery, a watchroom was incorporated into the tower, and featured four arch-topped  windows surmounted by matching curved stone pediments. The three-story brick dwelling was to be built over a full basement, and featured a gable roof with partial hips at each end. To provide the keepers with shelter during their numerous nightly trips to the tower to tend the light, it was connected to the tower by means of an enclosed timber-framed passage. A spiral cast iron stairway would its way up the inside of the tower to end in a circular service room at the gallery level, atop which was placed a decagonal cast iron lantern. A narrower gallery encircled the lantern itself to provide a platform from which keepers could clean the storm panels. As witness to the strategic importance placed upon this station, plans called for the lantern to be outfitted with a flashing white Third Order Fresnel lens.

Work at the site began in August 1873, and continued until the end of that year's season of navigation, when the arrival of winter made working conditions on the island untenable. The crew returned the following spring, and work continued throughout the summer and into the fall. Surprisingly, two "greenhorns" with no previous light keeping experience were appointed to staff this important new Light, with Orator K. Hall chosen as Acting Keeper and John Drouillard his acting First Assistant. Construction was completed in October, and Hall and Drouillard exhibited the new Outer Island Light for the first time on the night of October 3, 1874.

Click to view enlarged imageEvidently, acting Assistant Keeper Drullard was not cut out for the rigors of such isolated service, since he resigned from lighthouse service on April 27, 1875, to be replaced by Peter Ivory. Also that same year, a work crew returned to Outer Island to construct a fog signal building a short distance to the northwest of the tower, in which a single 10-inch steam powered fog whistle and boiler were installed. It is atypical that only one whistle was installed, since they were usually installed in pairs to ensure that a redundant unit was available in case the other was broken or needed to be taken down for repair. The whistle was set up to emit a characteristic repeated 60-second cycle consisting of a blast of 8 seconds followed by 52 seconds of silence. Whether as a result of the increase in workload represented by the addition of the fog signal, or whether he too was unsuited for the work, acting Keeper Hall was removed from the position on October 5th to be replaced by Henry Kuchli.

Click to view enlarged imageAfter the construction of a second steam signal building with a backup 10-inch steam whistle in 1875, life at the island remained relatively uneventful until 1882 when it became evident that the bluff in front of the station was eroding significantly, and a crew arrived at the station to work on building a revetment at the foot of the cliff in an attempt to stem increasing erosion. Understandably, the Outer Island keepers tired of having to carry all their supplies and coal for the fog signal boilers from the visiting lighthouse tender up the stairs to the station, and they were no doubt happy when a 242-foot long hand winch-powered tramway was installed up the face of the bluff in 1884. The tramway was improved further three years later, when a building housing a steam-powered hoisting engine was erected at the top of the tramway, eliminating much of the labor involved in taking-on supplies.

Click to view enlarged imageThe tramway received considerable repair in 1894, and was extended an additional 85 feet to allow the car to service both fog signal buildings directly. Also at this time, new brick foundations were installed beneath both fog signal buildings and the tramway engine house and a new hoisting engine was installed. Prior to the 1890's all fuel for the lamps was stored in a room in the cellar beneath the keepers dwelling. As part of a system-wide upgrade resulting from a devastating fuel fire, 1895 saw the construction of a standard brick oil storage house some sixty feet to the southwest of the dwelling. Outfitted with an iron roof, door and shelving, this building was specifically designed to minimize the possibility of a spreading oil fire. Also during this year, the Outer Island keepers were kept busy shoveling 26 tons of coal into the fog signal boilers to keep the whistles screaming a station-high 478 hours.

Click to view enlarged imageThe lighthouse tender AMARANTH arrived at the island late in 1900 and delivered materials for a number of planned upgrades to the station. However, arriving as she did so late in the season of navigation, the materials were merely unloaded and stored on the station grounds until work could begin the following year. When the work party arrived the following spring, their first order of business was the combining of both fog signals into a single building. Fog signal number 2 was taken down and moved close to the east side of building 1, and the two were connected. The boiler and piping for signal 1 were replaced, and the entire plant was re-plumbed and overhauled. The boat landing was rebuilt and filled with stone, and the section of the tramway from the top of the bluff to the new fog signal building was rebuilt.

Click to view enlarged imageOn September 28, 1905, a gale with 90 mile an hour winds whipped the water into one of the worst storms in memory. When the gale subsided it was found that a total of 30 vessels had been wrecked with 78 seamen losing their lives. During the height of the storm, the steamer VENEZUELA with the 337-foot 3-masted schooner-barge PRETORIA in the tow were passing off Outer Island. The tow rope snapped in the seas, and the VENEZUELA drifted out of control until her anchor took hold a mile and a half off the island. Her ten crew members managed to board a life boat and began rowing toward the island's shore. However, a huge wave flipped the life boat before it could make the island, and five of the crew members perished. , The remaining five crew members were saved by the Outer Island lighthouse crew, consisting of Keeper John Irvine, First Assistant Thomas E. Irvine and Second Assistant Otto Olson.

Consisting of a pressurized system in which vaporized kerosene was burned on a mantle similar to the technology used in present day Coleman lanterns, the intensity of the light was thus increased from 18,000 to 110,000 candlepower. Also at this time, the characteristic of the light was changed to flashing white with a repeated 50 second cycle consisting of a 4.7 second flash followed by an eclipse of 10.3 seconds.

1929 saw the replacement of the steam powered 10-inch whistles with a pair of Type F diaphone fog signals. Powered by air compressors driven by diesel engines, these improved signals were not only significantly louder than the old steam-powered whistles, but could be sounded immediately when needed, without having to wait for boilers to build up a head of steam.

Click to view enlarged imageThe station was electrified in 1940, and the intensity of light increased to 140,000 candlepower. Finally, 1961 saw the automation of the station with the removal of the Fresnel lens and the placement of a modern solar-powered 12-volt DC optic. No longer needed to tend the light, keeper Theodore Schelvan left the station for the last time after having served the station faithfully since April 15. 1948. With the structures boarded-up, necessary infrequent maintenance to the station's illuminating apparatus was accomplished by the Coast Guard crew stationed out of Devils Island, which remained as the last manned Apostle Island Light Station until 1978.

The erosion of the cliff in front of the lighthouse first mentioned in 1882 continues to represent a significant problem at Outer Island. Between 1987 and 1881 the island suffered its highest rate of erosion on record, averaging a loss of one foot of bank per year. Today, the crest of the cliff is a mere 50 feet from the lighthouse and fog signal building.

Click to view enlarged imageThe automated light in the tower installed in 1961 was upgraded to a Vega VRB-25 solar-powered optic in 1992, and in 1999 the Department of the Interior appropriated $215,000 for an engineering assessments for the stabilizing of the shores of both Outer and Raspberry Island, which is also experiencing significant erosion in front of the frequently visited light station. This engineering study indicated in part that a return to lake levels of the mid 1980's combined with wet weather could result in significant loss of shoreline at Outer Island within the next 10 to 20 years.

Fearing that these two historic structures were in danger of toppling if measures were not quickly taken, Wisconsin Senator Russ Feingold introduced legislation in 2000 for an appropriation to commence work on stabilizing the bluffs on both islands. Congress responded favorably with an appropriation of $2,000,000 for the project, with work expected to be underway soon, ensuring that this beautiful station can remain standing for many future generations to enjoy.

Seeing this Light

For five days in July, 2002, we were privileged to serve as NPS volunteers, assisting Park Historian Bob Mackreth in documenting the condition of all the Apostle Islands Lights. Outer Island was the first station we visited on the trip. The station is a twin of Au Sable light, and shows all the ornate design element typical of the hand of Orlando Poe. An NPS maintenance crew was working at the station, rebuilding the fog signal chimney and  installing a new roof on the dwelling and covered way. I was amazed to find that fog signal building still contained all of the original diaphone components, and could doubtlessly be reactivated with relatively little effort.

While climbing the tower, I was surprised that Poe had included a small pull-out shelf in the weight pocket to allow the weight to rest during day time hours in order to minimize cable stretch. This is the only tower in which I have thus far observed such a detail.

Finding this Light

Apostle Island Cruise Service offers a number of trips among the Islands, many of which pass round Outer Island for some close up photography of the station. Every September, they play a large role in the two week long Keeper Of Light Celebration, during which they offer landings on the islands for close-up views of the structures.
